Had quite an experience staying here.
The pros:
Lijie was very nice, helpful and supplied us with everything we needed for the stay.
The apartment is in a good location, clean and had lots of amenities.
The cons:

Unclear check-in process. There were keylocks in the entrance but I never received a code or the host's phone number for contact. Only once I was buzzed in by another apartment did I get the host's phone number.
Security: on the 4th night of my stay, someone came into the apartment and stole 2 MacBooks. We had to contact the police and filed a theft report. The place had no cameras and had obsolete security measures (you could technically create a copy of the lobby and apartment keys after checking out and enter it whenever you want). I was reimbursed by AirBnB for 1000$ and the host returned most of my stay. The host also updated us that they've done some work on increasing security in the premises.
