Hiya... I've lived in a few bedsits in my time, and they've all been okay.
Bedsits, at least in Glasgow, where i stayed, are usually the homes of students, and people sort of one-step-away from homelessness, so they're never going to be brilliant. The ones i stayed in were always badly decorated, and not very clean, but i cleaned it myself, and gave the walls a fresh coat of brilliant white emulsion, and it was fine.
Luckily, all the besits i stayed in had little kitchenettes in the rooms, so i didnt have to share a kitchen with anyone else. They had little electric cookers, fridges, and a sink for washing up. The only bad part was the sharing of the bathroom. In one place, the landlord came daily to clean the bathroom. In another place, the other 2 bedsits in the flat were occupied by men... and they were not very good at doing their share of cleaning , so i ended up doing it all. I was the only one who had a job, so i was always up first in the morning, and i cleaned the bathroom before i used it every day. UGH.
You might want to check what the situation is regarding utilities... in one bedsit, the electric was paid by the landlord, included in your rent. In another, there was a coin operated electric meter... keep an eye out for these, and if you end up with one, make sure you save all your 50p coins!!
One flat had a pay phone by the front door, another had nothing... so with the landlord's permission, i had my own phone installed. This was a long time ago... before mobile phones, so it probably wouldnt be an issue now that almost everyone has a mobile.
Hope that helps....
