Sei is a very helpful host. Everytime we chat her, she will directly response to our message. Her house is nice and clean, the wifi and heater working properly and the environment is great. We've come in 1 am and it is very easy to find the apartment since the guidance is very clear. We have no problem in communicating with her as she is very fluent in english. The environment is very quiet and safe. It near food store that open at 1 am.
