Our stay in Madrid was awesome! It was really nice of Cristofer to wait for us to do the check in, we arrived around 12 am or even later and he was awake to welcome us. We understood each other somehow in Spanish, as he doesn't really speak English.
About the room, it is indeed small as in the pictures, it is a bit hard to move around but except that it is clean and nice. We had everything it's said in the description.
I would suggest to get a hair dryer though because it's useful especially for the girls.😄
