We had a lovely stay at Jules' apartment, we were 5 people (2 couples and a single person) plus a little doggie. We all had our own room with bathroom, which gave us enough privacy. On top of this, the hosts gave us great tips for discovering the neighborhood, with some many choices closeby and in Madrid in general, having a trusted advisor for choosing restaurants was a treat. They were great hosts to the doggie as well, making sure he had all what he needed.
We couldn't recommend more this apartment and its hosts.
