Everything was done fine by Carlos. It was easy to communicate with him (nice attitude and no language barrier). We were introduced with plenty of options of what we should see during the visiting Barcelona and how it would be reached the best way (preferable timings, transportation sites, main features of particular areas etc.) All the basic needs for living were provided. We felt safe and comfortable in the apartment. So, all mentioned above, favored the trip to be pleasing and we enjoyed it much. Thanks to Carlos for that!
