We loved our stay at the Treehouse! The neighborhood felt very local (less touristy), and there are a lot of great coffee shops, bars, and restaurants nearby. It was an easy walk to the major sites in Madrid - El Prado, the modern art museum, and the Palacio Real de Madrid. We didn’t mind the trek up to the unit, but it is a LOT of steps and not the most straightforward entry. If you aren’t as mobile or just don’t want to carry bags up 5 flights of stairs, this is probably not the best spot for you. The ceilings are also a bit low, so tall folks should proceed with caution. It’s a great spot for a young person/couple who want to be in the heart of a fun, local neighborhood.
