A small yet perfectly formed little apartment which I'd recommend to any couple looking for a place to stay in Madrid. Location is ideal for exploring the city on foot or via metro (there's a stop directly outside).
Álvaro was a great host- helpful but not intrusive. He gave me directions on how to navigate from the airport to the apartment that were spot on and let us check in at a time that suited us. He also had left a few thoughtful notes and recommendation of activities near by.
If you don't mind a slightly smaller apartment and a few flights of stairs then definitely consider staying here. I certainly wasn't disappointed and wouldn't hesitate to recommend.
