We really enjoyed our 4 night stay in Mey’s apartment.
It was very clean and comfortable and had everything we needed.
The check in was very straight forward, described very well with easy pictures. The apartment is in a great location with some lovely small bars and cafés/restaurants very close by and the city centre less than 10 minutes walk away.
We could walk everywhere we wanted and only needed to use the metro to get from and to the airport (which is also very easy).
Madrid is a great city and Mey’s apartment is a great base to explore it.
