Edu is a wonderful communicator - quick to respond to any questions or concerns. He also had some nice dining and convenience recommendations.
Location is the best thing about his place. I stayed for six days with two cousins there, and we walked everywhere, which really allows you to soak everything in.
The suite is very well air conditioned and has black out curtains, so it's awesome for sleeping as well.
Conveniently located close to main town square, restaurants, cafes, attractions etc.
Only caveat I'd provide is I'd say the suite would be very tight for any more than three people.
I would absolutely stay here again when coming back to Barcelona.
