My family had a wonderful time in Barcelona especially staying in the apartment. The location is very much accessible to the metro (train) station and local stores (cafe, bakery, fruit stand and convenience store). Across the street is the taxi station which is very easy to get a taxi going to the airport.
The apartment was very cozy, clean and very homey, perfect for a family staying for a vacation (especially if you have kids). I personally like how each area of the apartment has been fully utilized and maximized.
The hosts (Zhou and Shanmei) are very gracious and welcoming. They have provided towels, drinking water, and biscuits to name a few. Apartment is well furnished and other appliances are ok to use (washing machine, hair dryer, tv and wifi and aircondition).
Overall it is a very pleasant stay and great experience! We will recommend the place to friends who plan to travel to Barcelona!
