Wally was an amazingly friendly host. When we got to the apartment, he spent a good half hour showing us the apartment, and recommending places to see and restaurants to eat at, categorized by neighbourhood. All of which was really helpful! His apartment was conveniently placed a really short walk from the Sants train station. It was a lovely and clean 200 year old apartment with a modern twist to it. Overall, our stay in Barcelona was very pleasant thanks to Wally and his accommodation :)
