Our stay at lijie's apartment was wonderful. Her communication was fantastic and she was on hand with any questions we had. She provided us with maps etc leading up to our arrival which made it easy for us travelling with 4 kids! The apartment is in a safe part of the neighbourhood and was a couple of minutes walk to Tetuan underground train station, which connects you with all the popular tourist destinations. Hop on off bus can be caught about 10 minutes walk to Arc de triomph. There is a supermarket right underneath the apartment and sone beautiful restaurants in walking distance, as well as high end retail stores. I'd highly recommend a stay at lijie's apartment if you are going to Barcelona!
