I've moved to a new flat and realised quickly I might have made a mistake!
there is a front door into the entrance lobby then a 2nd door to the stairs and lift. both doors are keycarded so I can get in just fine.
however for my guests, they can call my flat and I can open the 1st door but I can't open the 2nd door so I have to go downstairs to open it myself.
and to make it worse, there is a daytime concierge in the lobby. he seems to take it on himself to greet each quest and ask them where they are going so he can helpfully direct them.

I've only had 1 client here so far and I'm starting to worry. 6 month lease.. I will be relying on part-time escorting around my studying to pay the bills.

I'm thinking, daytime clients longer bookings only, meet off site for coffee then walk in together so the concierge will not bother us. maximum 2 daytime bookings.
evening bookings I will just have to go down and meet them myself, other residents will very likely neither notice or care. max 3 clients over an evenings.

also there is a back entrance which is keycarded but more discreet during the daytime so I could bring clients in without going past concierge.

written down it sounds like it could work however I feel really nervous about it. I'm worried about not being able to work here. I know it's gonna be more of a hassle with having to meet each client outside but not something which will prevent me from working.

I have the option to continue my 6 month lease in another flat which I'm viewing tomorrow but moving there wouldn't be possible for another 6 weeks. That building also has a concierge I think but it looks less posh so it might be more workable (concierge is more in a back office rather than meet-and-greeting all visitors).
I've also sent enquiries to a few local strip clubs, just in case.

why did I pick this building 

Ahhh, no this doesn't sound workable at all. Not just for the impracticalities but it sounds super stressful! It took me a while before I found THE ONE.

How many days do you work? And you aim on seeing either 2 clients through the day or 3 clients in the evening, or 5 in total per day? I know you said you will focus on longer bookings. I don't know about you, but I generally get 1 hour bookings, some half hours and maybe just 1 or 2 bookings per week that are longer than an hour. Will holding out for the longer bookings be feasable?

I would suggest that you go see the other flat. Try working as discreetly as you can and maybe book a hotel one day a week to take the heat off from your flat?

I agree that it is workable from the back entrance but it will be more stressful but think of it as being practice and not a long term thing. Obviously you will require to be dressed in "sensible" attire when receiving them at the door, but that shouldn't be a bother. Six months does seem long term but it's not really.  I would also take the six months to browse for an alternative location.

Make out a list of things you need to look for in a new apartment and the things you have come up against in this apt should be top of the list of things you DON'T want.

It can take up to six months to find exactly a flat that is totally suitable.  It's amazing the number of flats that are totally unsuitable for us, eg one with a concierge is near the top of unsuitable. 

Personally I had about a twenty point checklist of what I wanted, but "I wants" don't always get but it was a start.  For example, Is there a concierge? Yes? Pass on to next flat; if you get by front entrance without problem then it's onto location on landing, how many overlook front door, best if answer is nil, but not always possible; can you seeing oncoming clients driving into parking area, this is a godsend if you can for 100 reasons; does the front door have a spy hole, IMO this is a very necessary thing, for I didn't like answering the door in a hotel when there was no spy hole, you can always open door as clients approach if you see them and thus neighbours are unaware of the entry.

These are just a few pointers.  I'm just thinking it may be good to get a "sticky" written out for something like this.  Maybe there is one I don't know about 

All the best with your flat though.  Try not to stress too much, not easy, but it is possible with practice.

Okay I've been to see the other flat, it was definitely very workable. But when I called this afternoon to ask about moving someone else has applied for it. So my only chance of moving from here has gone

I've been offered a room in a shared flat for ?40 a day but I think that's more risky. Do agencies provide flats to work from?

I'll just have to work after the concierge goes home (4pm), meet client in back entrance, no daytime bookings at all, etc. Hopefully I'll get some work in a lapdancing club and do some hotel outcalls for some extra money.
This is gonna be a right pain in the arse, can't believe I'm stuck here for 6 months! Any idea how much lap dancers earn?

If the concierge sees you walking inside the building with different guys, and them those same guys walking out after an hour hmmm... I give him a month to put 2 +2= 4.  There's the possibility of him turning a blind eye, but that depends on the "building politics" that we don't know how friendly they are towards WG's. Some bulding management don't care, but other's do.

Like an above poster said: I would be using the back door. Problem is if there's CCTV  in the back door and you don't have a buzzer,  you'll have to step down to open the back door and eventually mngt will figure out what's going on. Of course it will take much longer for them to figure out than if you use the front lobby.

I have worked for [removed] in the North East and they had some flats for incalls in the Gateshead/south Newcastle area. Only thing was that they took a third of your rate. Not sure if its still the case now , but might be worth a try.

This is such a nightmare.
Do you reckon they will be checking CCTV after the concierge goes home? I was hoping to take a few bookings in the evenings.

They don't check CCTV unless there's a good reason for it. In my last apartment I had CCTV too, I was being extremely low key and careful with my traffic, one year into my lease there was a robbery in the building, so they started to look into the tapes and that's when building management noticed the traffic into my apartment. They did ask me about it and I told them I was doing a massage course and practising at home with friends (lol). One day when I was not at home the landlord went into my apartment and looked around (my neighbour told me) to see what was going on I guess, thank god he saw the massage table so he must have believed the story because he never said anything to me again. But I was also the perfect tennant, meaning, always paying rent in time, never complaining or causing any problem, being very polite to neighbours and I would always tip the building cleaning lady and keep her happy. Believe it or not these small things matter.

I was thinking like Paris!

Were you counting on working to make the flat affordable? You may be able to work from hotels. It's not ideal but it can be done.
