Overall we had a wonderful stay in Carlos' apartment. It looks exactly like the photos and the balcony is beautiful and spacious. The bed in the master was very comfortable as were the pillows. We did not use the other beds but they look like they are of great quality too. Even though is was cold most of the time we were there it was a great value to have a/c in all the rooms. When we did use them they worked beautifully!
The location was good and close to the main shopping streets. Also very close to several good restaurants. We had breakfast at Cake & Brunch - excellent! We also had dinners at the following places: Robata Sushi and Grill, Cheri, MariscoCo, and Patron. All of these were with in walking distance. We also made the trip via Taxi to El Nacional which was a nice experience. Food was very good as was the wine.
Carlos was a great host although we did not bother him too much. He did help us with any questions we had. He was a delightful person.
The only negatives we have: The apartment could have been cleaner, the towels were sour but since we had a washer and dryer we cleaned them. There was an odor coming from the bathroom with the vessel sink drain. We were told not to close the drain because we would not be able to use the sink - but pretty early on we closed it because the smell was getting too strong. That fixed the problem. Also there were some other maintenance issues that needed to be tended to which I'm sure once the high season has come and gone Carlos will take care of these things.
Only suggestion we have is to add a notebook with tips on how to use things in the apartment, WiFI name and password, what to do when you check out and so on. Adding a notebook of "Carlos' Suggestions" with what to do while in Barcelona and restaurants to go try and a street map of Barcelona would be an great benefit.
A must do: go see Gaudi's La Sagrada Familla. Best to do a tour. We had Anna and she was awesome. This church is unlike any Basilica you will ever see. Stunning!
Overall we had a wonderful time staying in Carlos' apartment. Thanks for sharing it with us!
