Ale, Maria and Arthur were all excellent hosts. They were very quick to respond if we had any questions and were flexible in allowing us to leave our baggage in the apartment corridor as we had a late flight.
The apartment was also excellent, the bed was very comfy to sleep on and it had lots of useful amenities like hair dryer, towels, ironing board etc. In addition it is in a great location in Barcelona, (quiet but not far away from the areas of interest). One of the shops around the corner was open at 3am and there were bikes to rent right next to the house!
