Our group of 5 (3 adults, 2 kids) stayed 4 nights in July for our family vacation. It was convenient to access the Niagara Falls attractions, groceries, beer/wine and local restaurants.
The house was spacious with plenty of room to spread out. The living room had a Roku with the tv to watch anything you want during your stay (you must login to your own account). The kitchen had ample supplies to be able to cook a meal. The central air conditioning was a welcome retreat from the summer heat. Everything was clean, the beds were comfortable and it was great to have 2 full bathrooms.
As mentioned in other reviews, the back yard was in need of attention and is shared with the neighbors. So I wouldn't suggest planning to spend any time in the back yard.
We had originally believed we would have access to the washer/dryer. After contacting the host, he pointed out that the listing states it's available for stays of 7 days or more. I checked the listing after that, but still didn't see that mentioned. As of this writing, the listing does indeed show this fact. Perhaps it's visible on the main website, but not on the mobile site? Regardless, we enjoyed our stay and would definitely stay here again.
