Carlos was very welcoming, the flat is in a great location (very near Old St tube and a supermarket) and I was impressed with the thought that had gone in to all the little touches. The flat is a little frayed around the edges, but was clean (more important), good value and was everything I was after.
I stayed Wed - Sat and didn't have any problems with late night noise mentioned in the ad (although didn't get in 'til quite late on Friday night, so may have missed the worst). One thing was that the blinds are quite thin, which did let in streetlight after dark. Not a problem for me as I never have trouble sleeping, but I imagine it might be an issue for light sleepers.
