Carme is a very nice, thoughtful host. She can speak 5-6 languages and knows Chinese culture well. She can even do calligraphy!
Her house locates in a quite neighbourhood near the Camp Nou. It's about 10 minutes walk to the stadium. Metro line 3 is within 5 minutes walk. The room we stayed at was clean and tidy, well equipped. I'll definitely stay at her place when I visit Barcelona again.
