Very helpful a welcoming host will make you feel at home. Carlos is always happy to give you advice and information.
The room is big and nicely decorated with a private balcony. You share the rest of the apartment with Carlos and his flatmate who are both friendly and very discreet. Depending on your personal criteria cleanliness could be improved as well as the breakfast.
The location is good, though you're not in the historic centre, it is close to the subway with good connexions to the rest of the city and airport. Very good area if you want to enjoy Barcelona away from the crowds of tourists of La Rambla.
Overall it was an enjoyable stay and we wouldn't hesitate recommending.
