Great location! We had some doubts with regards to the noise since the apartment is located on the main road, but we did not have any problem with this at all. The apartment is at the 7th floor and there are some heavy blinders that help a lot. The apartment was very clean and perfect for our needs. Very close to the metro station. The only downside in our holiday was that we had only one key, which was a bit inconvenient since we were 4 people not always willing to attend the same program, and even though we asked for am extra one the host did not give us any reply. Other than that we had a very nice experience in Madrid and the accomodation was a part of this!
