It was a great stay at Alex's apartment! The apartment is excellant,very big, with all necessary amenities you need for your stay! We arrived very late, at almost 5 in the morning which was no problem for Alex who met us at the apartment and replied to all our questions about the city, where to eat, go out and so on. The location of the apartment is very good, walking distance from Sagrada familia and Avenida Diagonal if you want to go shopping. All in all, very satisfied with the stay, apartment and Alex as a host.
When I return to Barcelona I will definately contact Alex for accommodation.
