Overall I am happy with my stay in Carlos house. He spend a lot a time to guide on things to see in Barcelona. He shared few maps and explained the route to take to see each part of the city. He also send email with list of restaurants names in popular tourist places which are good and things to keep in mind when traveling in the city like pickpockets, bag snatching etc. The room was clean and close to supermarket and metro station. I felt it was worth the money spent and I would recommend to stay at Carlos house.
