Jiatong is a very nice and friendly person. The apartment is very nice but at the moment I WOULDN'T RECOMMEND it to anyone. The building is under construction (I mean, heavy structural work) with lots of dust. Due to that, the apartment doesn't have natural light as the windows are covered with protective plastics because of the work that is being done inside (common areas) and outside of the building. Also due to the state of the common areas of the building we didn't feel safe using the elevator. The shared bathroom had the door lock broken and the door didn't close (a main nuisance for an apartment to be shared by 6 persons).
That said I wouldn't recommend this apartment while there is major construction going on. And be careful if you ask the owner about the state of the work as I was informed that there was still "some work"...
