I stayed at Iryna's house for a full week with a 5 year old, an 8 year old, and a senior parent. I concur with previous, helpful reviews that the photos do not do this house justice-- it is even nicer and more spacious than it appears.
The kitchen had lots of spices and basics that made cooking at home a lot easier. The beds were comfortable and shower good! There is a comfortable TV room in the basement, but it only has DVD use (no cable and the antenna was not working when we were there). Iryna offered to bring over another TV to get the broadcast signals, but we didn't want it. The wifi was strong, so were were able to satisfy the kids' media wants on their pads.
Off street parking was nice, and we didn't use the car at all during the week, except to go to the grocery store (which is too far to walk if carrying a heavy load) and to visit St Joseph's Oratory. Otherwise, we used the convenient Viau metro station, which was about 2 blocks away (and an easy walk through a park).
For people traveling with younger children, that park has a play area but there is an even bigger and better one in the opposite direction on Ontario, and accessible through the dedicated bike path about a half block south, that winds through the neighborhood (and a dedicated bike lane literally runs in front of the house, so it's a great spot for cyclists).
The back patio is lovely, with a view of the tower at Olympic Park, which can also be seen from the main bedroom.
The neighborhood is almost entirely residential-- restaurants and convenience stores are not super close, and geared more towards families than nightlife. There is a small convenience store at the metro station, and another a couple blocks away. Although my French is atrocious, we had no problem communicating despite this being a predominantly francophone neighborhood (but I also heard Spanish and English at the playground). We never ate out in this neighborhood, traveling instead to Old Montreal or Plateau, where there are lots of options; both are easily reached by metro, but would be long walks.
Overall, I would love to stay at Iryna's again and am not at all surprised that she has so many guests return. She is a lovely host and her home is functional and comfortable, and the location is convenient and quiet.
