Our experience with Georgina has been definitely great. The apartment is located a central area (you can easily reach Gothic quartier and Raval by walking) and is full of good pubs and restaurants. You can also find a supermarket in less than 5 mins walking. The reception also lets you to deposit your luggage for some hours after the check out, so you can enjoy some time more the city before leaving. The only flaw we found was the check-in, because the flat hasn't been cleaned yet. Anyway the receptionist was very kind and the cleaning service required less than an hour to arrive and solve the problem.
I definitely recommend Georgina's flat
