We had the pleasure of staying here for 5 days, and were very satisfied with the apartment. The location was fantastic, especially for a family with young kids. There is a play structure right in front of the building, as well as many restaurants, so we were able to enjoy dinner and drinks in the evening while the kids played within our sights. It is within reasonable walking distance of the main sights of Old Madrid. We had no issues with any of the amenities (ie. wifi, appliances, etc...), or the check in/check out process.

I noticed a few other reviewers mentioned the street noise from outside. We found it to be fairly mild when the windows were closed, and from my experience, this is typical of larger European cities. Unless you are a very light sleeper, then I wouldn't think the noise from the plaza should be a concern.

All in all, it was a great experience and we wouldn't hesitate to rent this apartment again. Thanks Ramon!
