This place is amazingly located. You can easily access the go-to tourist places as well as some "off the beaten path" type places.
Ana was the one who greeted us on our arrival, and was incredibly welcoming and informational.
The place was clean and with everything one would need for a multi-day or week stay. Given its place in central Madrid, it is compact, but that should be obvious given its central location. Regardless, it was more than big enough to house our group of 3 with some room to spare.
Would 100% come back again!
