Cleofas (he goes by Cleo), has a place tucked away in the heart of El Gotic - the oldest part of BArcelona, and arguably the most vibrant.
He is fast to respond to any questions/concerns.
Your stay will feel as if you have a secret hideaway right in the middle of the busiest part of Barcelona for Tourism. Almost everything of interest will be walking distance - all of El Gotic, the awesome neighboring areas of Born (go eat there!) and Raval (go drink there!), and Barceloneta (go to the beach there!).
