Had a great three-week stay in one of the mini apartments. Very easy check in and Ramón was always available for communication or tips. Location is great. Close to the metro (which takes you everywhere) and walking distance from Madrid Rio park and the Matadero Cultural Center. The barrio is nice with lots of shops, restaurants, and an air-con public library you can stay in even if you don't have a library card. The apartment was mini but very well designed. On the floor you also have a washing machine for longer stays. The only downside, to be honest, was the noise from the street at night/early morning hours. Nothing terrible, but not the quietest of places if that's what you're looking for. Other than that, super recommended and great price/value.
