The room is small, but I actually loved it for that reason. The only thing that might annoy someone is that the bed is located above you, and therefore there isn't much space between the roof and you. Still, I absolutely loved this place. The place is absolutely ideal for single travelers, and is located right in the center of Madrid.
Luz is also an amazing hostess! She took the time to sit with me and tell me about some of the site in Madrid and it's surrounding areas. She was also incredibly available if I needed her and extremely professional.
I should say that we only spoke in Spanish, so I am not sure of she can speak other languages. I nonetheless enjoyed every second of my stay.
