Antonio’s apartment is in a great location, an easy walk to all the things you’d want to do in Madrid. It’s also close to the Metro and the Sol stop on Renfe’s Cercanías trains. It’s in the attic of an old building with a lot of character, so be prepared for stairs and quirks. A big plus of the attic level is that the overnight street noise (late night partiers) is pretty muted. All things considered, t’s a very good value.
