The small apartment is super central - the location could not be better for Madrid. You are in the middle of the action on sundays, when the famous flea market "El Rastro" starts. Also Bars, Restaurants, Cafés and a spanish bakery are around the corner and you can do your sightseeing program by foot, you don't even need the metro. Although the metro station is around the corner, the transfer to the airport is very easy. The apartment was very nice and clean, the kitchen was equipped with the basics. The only thing is, that the apartment is on the fifth floor (without an elevator) and not accessible with wheelchairs.
We did not meet Andrea or Tomas is person, but Tomas answered always very quickly and friendly.
