Just noticed I didn't turn on the notification of the app, so we the first day took out the door key with us by mistake. Hope didn't bring too much trouble to them.
It's a really good place. The housekeepers, their cats and dogs are so nice. The room is super clean, and the bed is super comfortable, hope I would have a bed like that. We stayed for three days, everything is perfect. You can walk to the subway station in 15 minutes, and the bus stops are even closer. Highly recommend!
