This is an awesome apartment! We were a family group of 10 people (ages 7 to 77), and we loved that the apartment was spacious enough to allow us to stay together in one place comfortably. We couldn't have asked for a better location. The apartment has balconies overlooking the Plaza de Tirso de Molina, which was entertaining. It is a hip little plaza with a couple of bakeries, restaurants, etc., as well as two full-service grocery marts including a 24-hour Carrefour. Almost everything we wanted to do during our stay in Madrid was within a 10 minutes' walk (or less) from the apartment. There's also a subway station conveniently right across the street from the apartment. We really liked being located on this plaza; effective window shutters in the apartment allowed us to turn the plaza off at bedtime.
The check-in process was easy, convenient, and mostly automated. Inside, we found the apartment newly-renovated, modern, clean, and quite cool. Truly everyone in our group was impressed. There was effective air conditioning in all of the bedrooms and living areas. The bathrooms were modern and clean, and the showers were straightforward. The kitchen was not giant, but was modern/new, well-equipped, and functional. There was ample flatware, glassware, and dishes, and the best set of kitchen/chef's knives I can remember in a rental. There was also a capsule system coffee maker with a generous amount of capsules provided by the host.
This apartment worked out very well for us. I would highly recommend it for a family wanting to stay together in one space. It was very comfortable and quite cool, and was a great value for what it is and where it is located. Thank you!
