Carlos’s place was fantastic. We arrived very late and left very early, so the 24 hour reception was perfect. The location is right next to Chamartin train and metro station which was the perfect hub for day trips and seeing Madrid. The apartment was clean and spacious. Carlos was great at communication and giving directions. Having been to Madrid many times before in the “touristy” areas I’m glad to have stayed in Chamartin because we got to explore some delicious restaurants (definitely recommend La Bomba Bistrot!).
