We had great time at edu's house. It is located in a very central neighborhood and for us it was perfect to explore Madrid. Check in and check out we're very uncomplicated. Edu has several apartments in his house and ours was on the top floor and the interior was decorated with his art and had a nice unique style. Some of the interior and the kitchen seemed a bit make shift which nervertheless fitted the style of the apartment. We will definitely come back the next time we are in Madrid.
