This place is ideal for staying in Madrid! Not only is it within walking distance of, well, everything - and situated right in La Latina (restaurant and bar central!), it's comfortable and adorable. It has air conditioning, which during the summer here, is a life or death situation. The apartment is equipped with everything one might need - shower supplies, lotion, cooking necessities, a blow dryer, a small washer and detergent, etc. Essentially, it's as if you're at home in Madrid during your stay. And Mario was always reachable for questions. Oh - prepare yourself for stairs; it's a climb!
Fantastic experience!
