Enrique and his family were great. They allowed us to check in early with our bags which we really appreciate.
The apartment was very modern, clean and the WiFi connection and speed was fantastic. It was a very cute apartment with all you need. Highly recommend.
Only two real issues - the heater and the stairs!
The heater they have to heat the apartment is weak and very small, it's literally a square attached to the wall and you can only feel the heat if you stand next to it. In the summer this apartment would be phenomenal, but for winter/fall - it's pretty cold. The heater couldn't really heat both the main living room area and the room. They did leave extra blankets which was definitely needed (and used) but it might have been more helpful to have individual room heaters.
In terms of stairs, please be aware this is on the 4th floor, and this place has a very small stairwell with NO elevators - so if you've got big luggage, good luck!
But the experience was great. It is so well located, literally 5 minutes walking from Atocha station and is basically across the street from the Reina Sofia Museum and only a 10 minute walk from the Prado, Buen Retiro Park, and Botanical Gardens.
That being said, it should also be noted, it's a little noisy, you're literally right above a main street but it's not too bad, and if you're tired enough like we were, you probably won't notice it.
Overall highly recommend.
