I agree with Kay - when I've rented a cottage before, the owner or caretaker has come by at least once during the visit. I would read reviews carefully, because this will often be mentioned (eg "The friendly caretaker Bill popped in every other day to make sure all was okay" etc)
I think if I was going to do this, I'd want to go and stay for a couple of days first without necessarily working and just see what it was like. Are there neighbours overlooking, is there parking nearby for clients, etc.
