We stayed here as a family of four, including two younger children. It was a perfect location for taking in all the sights of Madrid by foot. AirBNB at its best - the small apartment is ingeniously organized and designed to have everything the guest needs and not an inch of wasted space. We heard no noise. The owner met us and was very helpful in getting us oriented, including sending us personalized tips and suggestions after check-in. We were very happy that we had gone to some of the places he suggested. One thing for guests to keep in mind is that there is truly no extra space. If you are four people and have a lot of bags, those bags will have to occupy the sofa in the dining area.
