My experience at A&Y's place was not nearly like others before me. Up until we checked in, A&Y was communicative, but once we received our check in instructions we were on our own. We arrived late in London after driving from Cornwall and taking the tube in around 9PM. We were able to find the key to the place but unable to locate the actual place. We found the building but were unable to find the flat number (as someone had changed it on the outside, but this host did not know that as I'm not sure they've ever actually been to this building in person or at least not for a very long time). After an hour of going up and down the unairconditioned staircase with our cases, we tried our keys in the doors until we found the right one, the host during this time, was slow at responding and only responded by saying it was on the second floor.
Once we checked in, things were ok, at best. The place is in a neighborhood that is quite loud and since you need to sleep with the windows open it's very difficult to sleep as others have said. You do get a fan, but it's held together with a bread tie, so you have to sort of prop it up to use it and it's very, very small.
As others also said, it's very scarce amenities, so you only get one towel per person. You need to hang them by the windows so that they can dry by the next day.
The bed is hard as rocks, it's just as described as a futon type mattress and you only get the down comforter so if it's hot, just ditch the blanket completely.
The hot water tank appears to be for the entire building? Not sure, but you've got about 30 seconds of hot water and then it'll be an ice shower for you and the next person.
Part of the reason we booked the place was that we were in need of a washer/dryer. When we arrived we couldn't find one and I recalled seeing one in the images of the kitchen (the host since removed all the photographs of the place) and when I contacted him, he confirmed that it should be in the kitchen. I sent him a photo of the kitchen and after about an hour, he responded saying it was actually in the bathroom behind the bathroom door.
The wifi would really only work for 1 device at a time.
