The studio is really centrally located right on Plaza del Dos de Mayo. Perfect for a few days of exploring the wonderful city of Madrid. Contrary to its location, the place is really quiet, being located in a small courtyard, so you don't have any noise from the square. Communication with Carmelo was smooth and we were welcomed by his friendly son Diego.
Points to be aware of: It's on the ground floor so there's very little daylight coming in, and because it's a bit humid and closed off, there's a slight cellar smell, but nothing too intense :)
