Begoña’s unit is surprisingly quiet in spite of being in the busy Sol-Gran Via area. Super close to the metro stop Sol (and Grand Via when the renovation is done). Easy access to The Atocha train station as well as the Airport (via Renfe Cercanias service connecting to the Metro at Atocha Renfe — about 45 minutes and only €3-4). The apartment is clean and cozy. Begoña was great and quick to respond to our questions. I would stay here again on a future trip.
