Claudio's Gracia apartment is a treasure, and he is a splendid host. He was happy to spend time with us when he greeted us, pointing out places to see and routes to walk.
The highlight of the apartment, of course, is the terrace. If you're a bigger guy, like me, you may struggle to navigate the tight circular staircase that leads to it, but the view will more than reward your effort.
It's a certainty that we'll call on Claudio again when we return to Barcelona.
