We loved our stay in the Malasana neighborhood of Madrid. It is in a lively area, yet the apartment is quiet, with the best cozy sleeping bedroom and comfortable bed we've found in an AirBNB yet! The kitchen is well-equipped for whatever you would need if you choose to shop and cook, but with all the amazing restaurants why would you?
Maria is an amazing host-she is quick to respond and give advice, and will help you with any needs (like the 345 AM taxi to fly out!).
The apartment is filled with unique decorator touches, very modern and interesting; we only wish we would've stayed "in" more-but you know how tourists are. It was easy to access the 2 metro stations nearby, to get around the city, and even walk to the city center. We loved a couple of the neighborhood restaurants and Maria's suggestions. It was a great stay in Madrid and we would hope to return, as we didn't even feel like we began to explore all there is to do.
