The apartment is 10mins from Plaza De Espania, which is served by buses and Metro for easy access around the City. The are a number of attractions on the doorstep.
Alex is s wonderful host, when he says 'while you are here it is your home' he genuinely means it.
He gave us recommendations on places to eat and to visit and was very accomodating.
The two things that I think some prospective guests may have views on
1. Sharing a single bathroom - we didn't find it a problem even when he had the second room let too
2. Private rooms - don't have locks, they're just rooms in his flat, but again we didn't have any concerns
