The ad owner and the actual host are different people. The ad owner wasn't always quick to respond, I had to chase them. The host is a friendly Spanish lady and you share the flat with her and her daughter. They are very friendly and ready to help and easy to communicate with.
The flat is within what seems to be a block of council flats and hasn't seen decorating for a while. The room you get is the one with the white bed. The cleanliness overall is OK but not perfect. You're allowed to wear shoes inside. The bed mattress is very soft - I'm a fairly heavy guy and felt like in a hammock on it. Overall this place would suit someone who doesn't mind an occasional spot or crack here and there, needs basic accommodation and wants to stay more central.
