Emilio was a wonderful host! When we arrived he provided a map of Madrid with explanations of the different neighborhoods and recommendations for restaurants and bars. He stayed in touch during our visit via WhatsApp, and was always available to answer questions or give advice.
The apartment is well-located. It is next to the Lavapiés Metro station, and there plenty of cafes, restaurants, and bars nearby. The unit was clean and quiet, and the beds were very comfortable.
