Zhao's apt. is very spacious & handled our group of 5. He & his wife Shanmei actually stocked the fridge with waters & fruit drinks which we used & replaced before we left. Zhao communicated with us promptly prior to our arrival & his directions from the airport to his apt. were excellent. When we came up from the L2 line to street level, to OUR SURPRISE, his wife, Shanmei was waiting there for us & led us across the street to their apt. on the 11th floor of an apt. building. As others have mentioned, this location right across from the La Pau station on the L2/L4 line is PERFECT to access the sights around Barcelona---using a Metro 10 Ride Card it was about 1 Euro per person per ride. Their neighborhood has food shopping as well as various small restaurants within a block or two. Zhao & Shanmei were also very helpful in providing sightseeing choices & map/Metro directions to get to the various locations. Their helpfulness, thoughtfulness & generosity certainly contributed to our first-time & wonderful visit to Barcelona!!!
