The location of Ruben's apartment is perfect for exploring the major tourist attractions by foot! We were able to simply wander and explore the sights and streets nearby which was a very nice experience. The facilities are somewhat dated but that only adds to the rustic and cosy charm of the place. There was a slight hiccup during our stay with the heating but it was promptly sorted out. Ruben was always very responsive to all our queries and even allowed us to store our luggages past the check-out time. All in all, we had a great stay in Madrid and will definitely come back!
