This apartment was exactly what my sister and I were looking for during our week long trip to Barcelona. Communication was quick and easy via the app, we were able to check-in on a Sunday afternoon, and Peter gave us a full rundown of what we needed to know and answered our most pressing questions (like where the nearest grocery store was)!
The location is great! 5-15 minutes of walking gets you almost anywhere, and the metro is so easy to use to get around town. We were close to the action without being in the heart of the party, although I would recommend a pair of earplugs for the weekends, if you're plan to be in bed by midnight or before.
There was everything we needed to be able to cook when we didn't want to go out, and the view from the balcony were beautiful!
