Our stay at David's apartment was EXCELLENT! Although it was not in the "tourist" part of town, the bus and metro right outside the door got us there very quickly. We even chose to walk to the Reina Sofia and to Retiro Park so it's really not that far. The apartment was beautiful, very clean, and well-appointed with all one would need. Having an elevator was great as we had a luggage to get up. The apartment was also very quiet because of the double windows. It was very hot while we were there but the AC worked very well and kept us very comfortable. David and his co-host, Santiago, were awesome to work with. They were very prompt with the reservation process, the check-in process, and were helpful in providing restaurant options nearby when we arrived. I'd say their "customer service" was awesome and a very pleasant surprise as our experience staying with them was much better because of that. For those that are reading this review, if you are going to Madrid, then, without a doubt, you should stay here! You won't be disappointed.
