The apartment is clean and spacious. We had 6 people and it was plenty of room for us to have our own space. The kitchen was well equipped and we were even able to cook one night because our young children needed some relaxing time. The location is perfect and we walked to all the sights, plus there are plenty of good restaurants right near the apartment. As other reviewers have noted, the street noise goes well into the night. However, we knew this prior to booking, so we were ready and it didn't bother us, the kids slept like rocks. The host was helpful in recommending a Flamenco show for us and communication with him was very good. We would rent this apartment again if we were ever in Madrid.
