Carme is a very nice, thoughtful host. She learned the calligraphy in China before and knows can speak a little Chinese. Her house locates in a quite neighbourhood and about 5 mins to metro. Also very convenient to go to airport by bus. The room we stayed at was clean and tidy, well equipped included bathroom and shower room. The best thing is it have elevator!! I don't want to remember to put the 20KG luggage to sixth floor in Madrid.
I'll definitely stay at her place when I visit Barcelona again.
