Christina was very responsive to all my questions both before and during the trip, and provided useful tips on how to get to around etc. Also, there are a lot of maps, guides and tourist attraction leaflets around (up to date), which is really helpful to get a first overview.
I was travelling with a party of 7 and we we're set up in the upper floor with 4 bedrooms in total: two sharing a big bed each, another room with two singles and a fourth room with one single. One of the bedrooms with the double bed was a master bedroom with adjacent bathroom. The house has three bathrooms in total, of which two have spacious showers. We bed with had any issues of waiting for the bathrooms etc.
I spend the last night on the couch as a friend joined (this was cleared by Chrstina beforehand), and I wouldn't recommend it for more than one night - you can only really sleep on one half of it as the metal frame in the middle is very uncomfortable. Also, don't put the most noise sensitive person to sleep there, both noises from upstairs as well as the downstairs tenant will be audible.
Which brings me to the part I really want to stretch: like Chrsitina clearly states in the advert and also makes sure to mention and has you acknowledge in the time before check in is the fact that the house is very poorly soundproof. I'm not sure how common it is for apartments in Canada, but we were not expecting it to be that loud, to be honest. You can clearly hear when anybody is moving upstairs or using the shower/flushing the toilet. I could also hear the downstairs tenant quite clearly and I believe she was speaking in her normal volume, not shouting.
So, like it is clearly stated, this flat is not for you if you want to have any late nights that can get loud (e.g. drinking there), but if you have a quite conversation in the evening and move carefully, this is totally possible.
The kitchen is well equipped and the WiFi was working well.
The apartment is rather easy to reach using public transport and the neighborhood has a residential character, but is not too far away from downtown.
