Claude's place was great. Staying the center of Barcelona has its benefits; however, Claude's place was away from some of the noise and crowdedness. Poblenou is only 4-5 metro stops away to La Rambla and the center. The Metro is so well connected you can get around anywhere.
The place itself had AC which was critical for the heat wave that was present during our stay. It was a nice place and was nice to retreat to after a long day exploring. Poblenou itself had its own celebration the weekend we were there and it was really neat to so local citizens essentially having one giant block party. If you are looking to be a bit away from the busy center, this is the perfect place for you.
