We were in Madrid to see the city and stayed 2 nights at Lorenzos. Although it was a weekend he wasn't in the city he made sure that one of his roommates welcomed us and prepared sone infos sheets and maps. We haven't seen the roommates often because we just needed a bed during our city tour.

The room is light and with the windows on each wall the wind comes through the room so it is not too hot in summer.
Just the mattress was a bit uncomfortable but ok for 2 nights.
The location is also good because we could reach a lot of places by foot.
