This is the best place I have ever been as an AirBNB in Madrid, and I am from Madrid. It is a confortable, modern and clean apartment in the thick of the Latina quarter, right where some of the best and affordable restaurants of Madrid are. Steps away from the Rastro (a farmer's market on Sundays), the cavas (which bubble with nightlife), the Plaza Major, the metro station (so you are minutes away from the Palace, the Opera, the shopping areas in Fuencarral, Gran Via, Preciados, Colon). You literally cannot get a better location, period. You literally step out of the house and you are right in front of many fantastic places.
It has two rooms: one exterior and another interior. We travelled with our infant, and she slept without issue even if the nightlife was fierce. You often can find airbnb's in the center, but old contruction or cheap renovations. Not the case here, they put nice new doors and windows and you don't hear a blip.
It has an elevator, that stops in front of your door.
This was fantastic.
