Silver is a great host and she knows Barcelona so well. Before I arrived in Barcelona she already gave me a lot of worth advice about Barcelona tour. And when I arrived, she welcomed me so friendly and invited me to coffee. It just liked you are visiting a friend's house in stead of staying in some unknown person's house.
I had a great time both in Barcelona and in Silver's house. Recommend those who are going to enjoy Barcelona to Silver's house. And you can face Sagrada familia just in front. How amazing it could be!
