You should stay here! The apartment is located near virtually everything you will want to see in Madrid. (We bought a ten-trip metro pass at the airport but never used it.) Amazing cafes and bakeries are close by, and Plaza Mayor, the Palacio Real, parks, plazas, museums are all easy to reach. Barbara was incredibly communicative, with lots of suggestions for places to go and things to do. She also allowed us to check in early which was super given we landed early in the morning. The apartment is well-lit, comfortable and had everything we needed as a home base on our travels around Madrid. If we return to Madrid, we will definitely stay here again.
