I booked this trip very late (less than 48 hours before arrival) and the owners could not have been nicer and more helpful with my various questions before I finalized the lodgings. And they were great with many suggestions for things to do in the Kingston area, even giving us highlights of different neighbourhoods. And they were very prompt with the questions that came up upon arrival (although the info was just what I'd missed in the correspondence).
The bedrooms are very spacious, get a good amount of sunlight (but the sun doesn't blast in) and we loved that there were white noise machines on hand! I use one and they are very helpful. Since there's a RR line nearby, definitely good to have there.
I didn't try the Jacuzzi but my friend did and really enjoyed it. Would have liked to use the firepit but between the rain and cold, the weather just didn't cooperate.
The lodgings also offer a driveway so you don't have to use street parking. We appreciated that since we had various bags we brought in every day.
Since I did use my computer while I was there, the one thing I would have liked was better/brighter lighting in the living room. That's my only minor quibble with the place.
You'll have a lovely, welcoming stay in #A.
