This is one of the best airbnb experiences we've had. The apartment is absolutely gorgeous, spotlessly clean, home-like, warm (it was freezing outside), and amazingly quiet. It was such a comfort to get there each evening, after a day of walking. The space is huge, with three bathrooms, so there's a lot of privacy for each guest.
The location is incredible! we bought a metro card and didn't use it once, because we walked everywhere. There's a grocery shop right across the street for basic supplies, and a Lidl supermarket a few minutes away. The Prado museum and El Retiro park are within easy walking distance, and the neighborhood is lovely. It's an amazing apartment! I highly recommend it.
