This apartment was perfect for our family trip. We would definitely stay here again!
Obviously, the location is unbelievable - we were arriving by AVE train at Atocha Station, so it was wonderful to simply cross the street and not have to deal with taxis or public transit. We also took the Cercanías to the Airport at the conclusion of our trip just as easily. Finally, proximity to major attractions, restaurants, and grocery stores was excellent. Of course, it was quite busy outside the window, but the soundproofing was very well done so noise was not an issue.
The apartment was exceptionally clean on arrival, and just the right size for 2 adults and our 2 young kids. The kitchen had all the necessary devices and even a few extras that made cooking family meals simple.
We received excellent communication in advance from MADFlats associates. We had no issues at all using the app to open the building and apartment door, although on check-in an associate was available to guide us just in case. Physical keys were also available as backup, but we never needed them as the app worked flawlessly the whole time we were there.
Overall - this was our perfect hub in Madrid!
