We spent four fantastic days in Barcelona. Juan was a great host. He was very flexible, helpful and he tried to fulfill our every request. Although we've just briefly met, he gave us recommendations on where to eat and what to see.
The location was also perfect, in the city center, very close to every sights. The stairs are truly tricky, but you get used to it in to time.
All in all, if you're looking for a great location and a nice host, Juan is your guy.
