It was just great! Alex is easy to communicate with and was helpful when me and my family arrived late. The appartment is fantastic and the location is superb. It's close to most things in Madrid and with a vibrant nightlife just around the corner. If you prefer to stay in a calm part of the city, look for something else, but if you want to experience what Madrid is really about, this is the place to be! The appartment does not have a proper kitchen, but it has everything else, including great beds! We would gladly return any day! And on top of all that it is a good and creative project with the open source design furniture. Love it!
