My family and I LOVED Ruben and his apartment! My fiancé and I booked the apartment for us and my parents (four people total) for three nights. My parents decided to fly in a day early, and though the apartment was rented for that night, Ruben made special arrangements for them and let them stay at his own apartment for the night - what an amazing host! The apartment was fantastic - well-decorated (by Ruben himself, who is an incredible woodworker), spacious, and comfortable. Two things to be aware of: (1) the streets are a bit noisy at night, but that's to be expected in night-owl Madrid; (2) the bed in the second bedroom is a full bed, and cozy for two people, but if you're used to smaller double beds (or if the second room is for one person) you'll be fine! Ruben is the best host we've ever had on AirBnB - friendly, generous, accommodating, funny - and we loved spending time with him during our stay. Would highly recommend staying at Ruben's apartment(s) - you're guaranteed a great time :).
