Great location, ease of check-in and fast communication/flexibility by the host. We came for the winter carnival and walked from there to the old town. The massive snow storm added extra fun in climbing the hills and stairs on the way to the main event :). My only qualm would be that it appears nobody stayed in the studio for at least a month, because even though it was clean - the sheets smelled stale and there was strong sewer smell in the bathroom. The smell went away after flushing the faucet (per Tony's suggestion), so that wasn't a big deal. But if it were me hosting, I'd tell whoever cleans the room the day of to double check on those things and maybe re-wash the sheets again because we were confused if they were clean or not. That was the main observation.
The other observation is sound insulation with neighboring units. While nothing could be heard from outside, we could hear all the neighbors' steps/doors very distinctly. Again, for this price I adjusted my expectations and it didn't bother us as we were mostly exploring the city, but it's good to know in case there are people sensitive to such noises and plan to stay here. Other than that, everything else is just as described by others in terms of positive experience. Loved our experience in Quebec and people were super friendly and welcoming. Looking forward to exploring this neighborhood more on a summer occasion.
