We enjoyed the stay in this comfortable flat, which was very clean and exactly as shown on the picture. It had a perfect location, so we went on foot to all sightseeing spots, shops, squares and evening hang-outs. The only downside is that walls are very very thin, so it gets quiet only after all neighbours get quiet. Frank welcomed us in the flat, gave us fantastic tips for the city and restaurants - thank you for that! We really loved our stay in Madrid!
