I used to rent two separate places. It was a nightmare, too many outgoings and having to work doubly hard. The building was perfect, but it became a hassle. Tidying two places up, having to run from one place to the other sometimes at short notice, dealing with 2 different landlords etc became too stressful.
So I gave one place up, and now I am much happier working from home. I live in a massive anonymous apartment block, half the flats on my floor are empty, and the guy next door I have seen once in 6 months. Its also quite hard to get in my building without being buzzed in so I've never had anyone randomly knock on my door, and personally I don't mind sleeping in the same bed (as long as the sheets are changed).
I would like to move to a bigger place, but I'd be looking at another ?250 a month and I'd much rather save that money, especially as there is no major reason to leave.
