Paul is an excellent host and offers a nice apartment located in just next to a famous La Rambla.
The room we stayed in is basically a double bed and a huge closet, but you don't go to Barcelona to spend time and the bedroom, yeah? It's clean and comfortable.
Altough the flat is shared with the host, it's feels almost like a private apartment - Paul lives upstairs and is very tactful. On the other hand, he gave us ton of useful hints and we had good chats together.
