Cecilio was a wonderful host with a beautiful home! Looks just like the pictures with lovely decorations and clean rooms. My Spanish was a bit rusty so communication was a little bit hard, but never presented any real problem! To get to the major sights required figuring using public transport or taxi, which was sometimes a bit of a hassle, but to be expected in a city like Barcelona where many of the sights are spread out. We were there the weekend of the Catalan Independence vote which was very interesting as we saw a couple protests and voters lined up, but we felt very safe and felt no danger in the neighborhood we were in!
Overall good stay! Don't expect to be able to walk to the beaches or to the Gothic quarter but they are easily accessed by bus or taxi.
