Had a great stay in Madrid. Excellent communication and flexibility enabling me to arrange checkin. Cozy room, high ceiling, big closet, desk, able to use kitchen. Only the bathroom would score under 5 stars; nonetheless it was ok.
Fantastic location, nice neighborhood with everything you need in the immediate vicinity; very well connected by public transport to anywhere in the city and airport; also excellent for people who like to walk like me; right next to the Retiro Park.
Definetaly reccomended.
