Javier's apartment is awesome! My husband and I stayed there only one night and it was perfect and super convenient location. We were able to walk everywhere - Fuente de Cibeles, Puerta de Alcala, Palacio Real and even Parque del Retiro (30min walk). It's close to plenty of restaurants and shopping. It's also 10min walk from the 203 bus that takes you directly to Adolfo Barajas airport for €5. There's also a lab close to the apt where you can get your Covid test for flying. Javier was very accommodating and allowed us to leave our suitcases for a couple of hours after check out so we could visit some sights before leaving. The apartment was spotless clean and so comfortable! Definitely recommend staying here!!
