Xiaohan's house is nicely located in a residential quarter close to Waterloo's universities. You have very good connections to the main bus lines, and walking to lots of pubs, restaurants and stores takes at most 10 to 15 minutes. There are no pubs immediately next door, so there was no worry about the night's sleep.
The house itself offers a lot potential, but some of it is not used. E.g., when I stayed here, the living room felt more like a junk room; the nice backyard is just being prepared for summertime. The common areas are quite messy, but not disgusting.
The small room I lived is simple, but in good order; everything there was properly arranged and clean when I arrived. The kitchen was also messy, but everybody was dutiful enough to keep the inconvenience for me to a minimum. Again, messy, but not disgusting. People actually cook and eat there every day.
If you are sensitive about that, be aware that the non-smoking rule was not taken very serious. I did not care, and hence not ask or complain - I imagine that if you mind it, everybody will come to terms with that.
Talking about people, it's four in total. Xiaohan and everybody else there are very pleasant, friendly and helpful people. Xiaohan was very responsive, and while I did not see her a lot, everybody else was quite communicative, too.
I can definitely recommend Xiaohan's place if you are looking for a reasonably priced shared student flat and are an easy-going and laid-back type. If you are rather on the nit-picky or meticulous side, think twice, and let Xiaohan know.
