I found my stay quite pleasant. Jonathan was prompt in responding to calls or texts regarding our concerns. The ambient noise around the house is practically nil thanks to limited vehicular traffic because of the street layout, but it is near enough to the skytrain and transit that it is not a problem. The heating was functional and ensured that we were comfy while indoors. There is A/C too, but it was winter at the time and we didn't think it wise to try it out!
The interior of their home is furnished in a very personalized yet tasteful manner. The photos don't do it justice! Among the paintings in the house are those of their two dogs. There is also a painting of a bear in my bedroom that guarded my nightly slumbers (possibly not their pet, but who knows).
The mattresses were clean, although a bit too well worn such that there is a slight depression from frequent use that made it uncomfortable on my back. I had to sleep upside down so that the flat part was flush with my upper back. That would be my main complaint for this house, which would otherwise be 5 stars!
