The apartment is in a perfect location to explore Madrid and we walked pretty much everywhere to the Prado, palace, and throughout the historic district. Don’t miss the perfect falafel place 3 minutes away (Falafeleria).
The apartment has everything you need for a good stay and the large balcony doors are perfectly sound proof (which you’ll need since it can get pretty loud late at night).
The one problem we found (although none of the other reviewers mentioned it) was a persistent smell which the owner attributes to a paint or sealant used to resolve a previous flooding problem in the building. We found it to be an issue, although keeping the two big double balcony doors open helped.
Enrique was a responsive host and Jose was very helpful checking us in.
Make sure to attend a remarkable flamenco dance at the Flamenco Teatro minutes from the apartment.
