Zhao answers all enquiries prior to trip promptly and adequately. Check-in was smooth and his wife gave us the tour of the house as well. The kitchen was stocked with milk, bread and fruit juice on our arrival as we arrived quite late and on the bank holiday so most of the shops were already closed by then. The house was spacious and roomy just like in the pictures as well as clean. It was a 3 mins walk to the nearest metro station which is accessible to most of the tourist places and there is a bakery just opposite the house, fruits and vegetable store downstairs and a halal butcher shop 5 mins walk down the street from the apartment. This was most convenient since some of my friends and i were Muslims and we cooked most of the time. The apartment seems to be in a safe neighbourhood and there was a security system in the apartment whenever we leave the house. Some downsides were that the heater doesn't work well when 2 people use the showers at the same time, the living room has no curtains which is glaring and hot when we eat at the dinner table and that the sink seems to take a very long time to drain even when there was nothing blocking it. Overall this is a good place to stay when in Barcelona.
