It's been a few years since we visited Barcelona, but I've just booked two return tickets for next March (too much wine at dinner, and unbelievable EasyJet prices).
Last time we were there we took a bus (possibly the 24) from Passeig de Garcia to the East entrance of Parc Guell. On the way we passed through what seemed to be a very attractive area, with loads of shops and local restaurants.
A look at the bus route map suggests the road could have been Gran de Garcia. Is there a name for this area, is it pleasant, and is it an area with many hotels?
