Simply couldn't imagine any better place in Madrid to stay. Beatriz's apartment is most comfortable and spacious at an excellent location, everything is spotless clean and thoughtfully organised, I can say it's the best equipped apartment I've been to in all my Airbnb experience.
On arrival we were warmly welcomed by her brother-in-law, the wonderful Alberto, who gave us countless valuable recommendations; while Beatriz was most kind and check on us every now and then to make sure everything was fine, and responded virtually instantly whenever we had questions.
I'll definitely stay here again when I revisit Madrid!
