Excellent location and facilities- a...

Liked: Excellent location, right across the road from Wellesley station and short walk to Bloor-Yonge. Easy access with code or electronic key- no physical key needed! Excellent amenities with more towels etc available if needed
Disliked: Very small room- difficult to have suitcase open and still move around

It was safe and comfortable

Liked: Location, clean with a very good shower
Disliked: Very loud heater

Good

Liked: Great shower, good room if a little small, good location, self check in and access was super easy
Disliked: Slightly overpriced for what it was

Fine for my stay, wouldn't...

Liked: The location of the Sonder was useful and walkable to lots of the good bars and rtestaurants in Toronto but there are quite a few homeless people in the area - just something to be aware of.
Disliked: I was in the basement, which wasn't what I expected but the heating was on full blast which made my room absolutely boiling hot and so I had to leave the window open, which due to the level of the room, meant that was at pavement/sidewalk level outside, which I didn't love. It also made the room quite loud as you had to listen to everything going on outside. That isn't a huge issue for me, but worth advising people who need quiet to sleep. The TV didn't work either so I could only use the room to sleep and shower - not a huge issue, but worth pointing out.

Superb

Liked: Clean, bathroom, mattress, view from the window and the location.
Disliked: 1) I booked 10 nights. They only gave 2 packs of coffee. 2) No microwave.

Poor

Liked: The location is really good
Disliked: My room in the basement was so noisy, I heard the metro. On my last day the AC broke which was so hot about 28 degrees

Very good

Liked: locality, clean
Disliked: no desk to work at, room not refreshed daily ie coffee

Disappointing wouldn't stay here again

Liked: Good location easy access
Disliked: Bed had quite a bit of hair on it. Bug in sink. Very small and noisy. Beeping smoke detector in hallway all night.

Poor

Liked: Convenient location, steps away from the subway. Check-in procedure was very smooth.
Disliked: The room had a mouldy smell and everything was just not quite clean. It's a conversion of an old house, so you can hear everything from the hallway. At this price point, I'm sure there's other options with better cleanliness and similarly convenient location.
