We have been really happy about Gloria's place. The mattress was really good, the place and furniture well designed. The room and bathroom were really clean. Gloria is really nice and helped us out with the check-in. Plus really close to the centre of Madrid.
The announcement is not well described. In the profile of the room there is the picture of the other room and it's not clear that we would have shared the bathroom and the kitchen/living room. We thought it was going to be like that from the other feedbacks, which was more than ok for us.
A little problem with communicating with Gloria since she doesn't speak English, but most of the other Spanish people in town don't speak it so... Be ready!
Other than that, I recommend Gloria's place!
