Sergio was very accommodating and the apartment was fantastic. He was very hospitable, giving us local maps/tips/brochures, providing welcoming amenities for a nice stay, as well as even checking in with us frequently to make sure everything was fine and asking if he could do anything else for us. The apartment was clean and very nice for us two to stay in for four nights. The location was also a nice bonus as it's very close to the Atocha station as well as other local attractions. I would definitely recommend booking Sergio's apartment if you're looking for a nice private airbnb with a great location and a hospitable host!
