The first floor apartment on Calle Amsterdam is very nice. I would say it sleeps two couples (4 ppl) very well and the beds are very comfortable. The front room faces the street, so don't forget to bring earplugs if you're a light sleeper. It's such a great spot to walk from..to all the various neighborhoods for foodies, museums, cafes, churrerias, and more. Clau and Rodrigo were very helpful and communicative during our stay, and i appreciate their attentive approach to hosting. The building seems secure and I didn't see many people coming in and out because my friends and I were busy during the weekend. The main closet is massive and i wad a bit overwhelmed because i had a small suitcase 😅. Enjoy your time!
