Great option for a solo traveler. Location unbeatable, superb cleanliness, great communication with host Juana. We didn’t get to see each other much but she made sure I was ok during my stay.
Only small downsides: 1) internet in the room was a bit unstable, I had to work a couple days and videocalls were a bit challenging. 2) a courtesy breakfast is advertised but I didn’t get any indications about it.
Anyways, small details. I would stay again next time I’m in Madrid especially if I’m not working at all and travel king on my own. It is a great place if you’re just enjoying Madrid!
