We did not had the chance to meet Kai but he was very helpful and responsive to our text messages. The house is in a convenient location, about 7 min. from a bus stop and 15-20 min. walk from a train station. The location feels safe with restaurants and shops around the area. We had a little bit of a hard time finding the house, but just know that is the "blue house" in Thurlow and Comox street and you should find it quickly.
Our bedroom was #8 and was clean and comfortable. It had a small terrace. The bath was fine, although the bathtub a bit different for me. It's a tub with a hand mobile showerhead and a curtain. I had a hard time washing my hair the first day but then I got used to it :) I guess it's perfect once you get use to it because it helps save water. There were other 2 guests at the house, but were pretty quiet and respectful, they are living here long term I believe. Also you have to take your shoes off once entering the house so I guess this helps keep the house clean. We were happy with our stay and loved Vancouver very much!
