They are kind and polite, and do their best to make sure that you have a good time at their place. They give you water bottles, yogurt and fruit as breakfast and have different kinds of tea and coffee. I had issue with internet connection and Tang stopped by the place very quickly to solve the problem. The only thing that (absolutely) was out of their control (even they did their best) was the weather. During my stay the weather was super cold and their apartment is at the first floor, even though they provided me with the heater but still it was cold with the heat turned on. Thanks Tang and Kwan for hosting me. You both are so sweet.
