The apartment was beautiful and well equipped with AC in main room and bedroom. Wifi worked well in the main room and was a little spotty in master bedroom and on the roof deck. 2nd bedroom is small but we only used the master. Despite all the activity in the neighborhood at night, it is very quiet inside, and we had no trouble sleeping. There are two separate bathrooms and shower stalls. The masterpiece is the jacuzzi on the beautiful roof deck. It was perfect to enjoy a little Cava after dinner. The temperature of the jacuzzi (32 deg C) is not as hot as typical hot tubs, but it was the ideal temperature for the warm Madrid nights. We walked almost everywhere as the location was very central to many parts of the city. We had a nice breakfast in the square right next to the apartment and there are many stores and restaurants in the immediate area. Andreas was very nice to meet us a little early so we could drop our bags and start exploring the city after check in. We really appreciated all the great communication as well! We can highly recommend this apartment!!
