Nice location on a quiet street in the Chamberi neighborhood, the air conditioning and wifi work great and Luis was super helpful, letting me check in at almost 1 am after a late plane arrival. On the downside, the sofa bed is quite uncomfortable and there is quite a big gap under the apartment door which means that you hear everything happening in the hallway as if it happened in the apartment. It got a bit better when I started placing a towel in front of the gap.
