Location is good. Had difficulty in checking in at first as the instructions were not very clear. There are 2 doors, for 2 separate units. The key for the 1st floor is kept inside the lock. The confusing part was opening the 2nd floor as part of the instructions were written in Chinese. For the 2nd floor, the door is open by punching in the code provided and then turning the knob to the left. And for locking the door, just have to turn the knob to the right and it get lock. The host also mention that the door to the 2nd floor can also be open using the key. For the initial check in, am not sure whether the key is needed or not for the 2nd floor door as we did.
