We had a wonderful stay at Miguel's place! The apartment is beautiful, the neighborhood is lovely (El Rastro takes place just outside the door on Sundays!), and there's a lot to do in the area. Miguel is kind, responsive, and a great host.
The pull-out bed is quite comfortable, though we did have a bit of difficulty trying to sit on it (when not pulled out) as it was rather slanted. We had three people in the space and while it was small, there were lots of nooks and crannies for storage. This was the perfect home base for exploring Madrid!
