Carlos is very nice and hospitable. He greeted us on time at the apartment even we had a late flight to Barcelona. He introduced Barcelona in details and made good suggestion to our travel. The apartment is very clean and tidy with a lovely living room and balcony, and is in a perfect location that is safe and central, making all the key sights easily accessible. We really enjoyed the stay at Carlos' apartment! The welcoming bottle of Cava tasted very nice as well. Thank you Carlos!
