I believe is the best location in Madrid and clean. But be aware they have 57 others rooms across Madrid.
we agreed to meet at 2:00pm we dont here from him until 2:35pm. And I was frustated with my two parents (75 years old each). In the middle of a little street trying to find wi fi to contact him.
It was a good place but of you are running 57 rooms in different locations make sure you commit to hours.
If at least he sent a message that he was late at least I was able to wait for him in a restaurant not in the middle of a street guessing when he come for check in.
