We had a wonderful stay in Carlos's apartment. The apartment is situated in the heart of Barceloneta, just steps from the beach, and a short (10-15 minute) walk into the beautiful Gothic Quarter where you can see Barcelona's oldest, very picturesque streets, tons of hip boutiqes, and good restaurant. Barceloneta, being a very touristy beach neighborhood can be a little pricey, but there are definitely many affordable food options if you stay off the main drag and explore the more residential streets off the boardwalk area.
The apartment itself has an unbeatable view of Barcelona where you can gaze out and watch the sun set over the city from the small terrace. The apartment is nicely laid out with a good sized living area, and fully stocked kitchen. The master bedroom is huge, with ample storage and a lovely window view to look out to.
The second bedroom is VERY small. We were not prepared for just how small and dark it was. There is no window, just an opening to an interior air shaft. For a family traveling with children, I think this room could be just fine, but I would NOT recommend this for two adults. I found the room extremely claustrophobic and ended up sleeping in the living room, which worked out just fine.
Carlos and his girlfriend were extremely responsive at all times during our stay. We had a few very minor issues which were resolved within minutes, and the team could not have been nicer to us. We were so so grateful that they let us leave our bags in their own apartment between check out and our flight time.
Overall, this was a great experience and perfect base for exploring Barcelona. We would come back here in a second!
