My husband, dog, & I stayed here for a month. It is an absolute precious space. They even had dog bowls and a bed set up for my dog which just warmed my heart. The biggest downfall is that there is zero privacy, but assuming no one goes to Madrid with a complete stranger, you’ll be alright. We did have an issue come up, so I texted the host and she replied that her husband was on his way! Absolutely amazing hosts, and she checked up on us throughout to make sure we didn’t need anything as far as supplies or even recommendations for the city. Also, we walked EVERYWHERE! I wouldn’t want to stay too much in any other direction because then you wouldn’t be right in the center anymore. Definitely would stay here again if we were to return!
