Zhao is a great host, we were able to communicate easy and fast through whatsapp. He also was available to receive us on metro station. His house is quite spacious, besides to be well cleaned, with a good location and modern. One of the main plus is the proximity of metro station, is almost on the building door, so you can reach easily any touristic spot at Barcelona. We liked very much staying at Zhao´s apartment and definitely recommend the place.
