Alba was a brilliant host: excellent communications; flexible about when we arrived and checked out, and gave us a really warm welcome.
The apartment is beautiful - everything you need is there, there's a balcony at the back, air conditioning (perfect for hot Barcelona days) and it's only a 20 minute walk from La Rambla, although we only made it there on our second day as the neighbourhood was great - shops, restaurants, cafes right on the doorstep.
Highly recommend and will definitely stay here when next in Barcelona.
