The host, Kenny is very nice and caring. He'll recommend you some of the popular food that are nearby the apartment or which places you should visit. He even send a text mesage to alert us that the weather will a bit colder the next day etc so we should wear thicker clothes to be safe.
There's a security guard at the lobby all the time which is very safe and this place is only a few minutes walk from the famous ximending shopping area and ximending station exit 1.
