Very happy with my stay at Javier's place! I arrived late due to delayed luggage, but Javier was kind enough to stay up and wait for me and received me w/a smile at 12:30 AM. The apartment is nice (well-decorated, with lots of personal touches from Javier), the room is quiet (with some dangerously effective blackout shades!) and it couldn't be more centrally located--close to multiple metro lines with most attractions in central Madrid within walking distance. Javier works from home most days so was on-hand to answer questions or to give recommendations. He's also a super friendly guy--couldn't have asked for a nicer host. Highly recommend Javier's place for solo travelers!
