I had a wonderful stay at Ying's place. Although she speaks little English, we managed to communicate quite well with the help of Google Translate. Ying and her husband are friendly and caring hosts, they even prepared a breakfast for me every morning. The room is tiny, but contains all you need. And you'll be out exploring the city anyway… The location is great, within the remarkable Eixample district and 5 minutes walking distance to Espanya square.
