We met Antonio very briefly and he was very pleasant. He was nice enough to let us have a late check out.
His studio is somewhat quirky and is located in a perfect location: very near Gran Via (where all sorts of shops and subway stations are), a few steps away from Chueca (where lots of bars and clubs are), and if you're like us (the kind of tourists that like to walk around a new town), you can get to the Prado Museum in an easy stroll.
