Nice little apartment in a great location. Concepcion was very easy to communicate with, and the check-in/check-out system was great. The apartment was nice and clean, with a comfy double bed and a good shower. Being close to Atocha Station is great for travel by local and longer-distance trains, and the airport bus leaves regularly. Retiro Park is very close too, and there are plenty of bars nearby to get a coffee or a beer.
