Easy to locate, even if we did start walking the wrong way from Union Station like the tourists we are. Conveniently close to food places and a Dollarama for random potato chip purchases. Easy to access, room is comfy and contemporary. Would recommend as a great option.

Disliked: Amenities
Not a fan of online registration process from email, moreover the email for registration looked like SPAm and I didn't checked it, only to spend 30 mins at checking desk to fill this form on a slow network. The good old way of checking in at a reception counter was there for a reason. You could probably install a kiosk like airports to check in

Stayed here for a few days visiting Toronto to see a few Blue Jays games, hotel was clean and the app was easy to use for access to the front door and the hotel room. Also close to a lot of tourist sites, will stay here again when I come back!

Location was definitely excellent. Close to everything being in the Entertainment district of DT Toronto. Short walk from union station, close to the ball park and transit, etc. The area is probably for the younger crowd - noisy every evening with bars and night clubs just below you and with trucks and coming and going at all hours of the night. We are in our mid-50s and not in the "scene" anymore - Lol... Ask of a room in the back of the building or a higher floor may help with noise. Had problems with the mobile key working and not working, but I think they had some of their staff working the front area during the day.

Great location. Clean and comfortable accommodations. The high, deep tub made it challenging to get in and out of the shower. Not suitable for individuals with mobility problems. Otherwise, a nice stay overall.

Perfect Location

This was a pleasure trip and I wanted to be near the Arena's. 100% perfect location! Clean, easy to access, affordable and a less than 15 min walk to HHOF, Scotia Arena and the Roger Center. If you like Pizza, Grand Assembly is right across the street. Well worth it!

Overall, I had a comfortable stay. Generally well-maintained, although the bathroom could have used a thorough clean (lots of little hairs in the bathtub).

All good except the confusing “white box” at entry that was not white and I could not find it in the rain at night because it was black! Very stressful when it’s raining and I got in after midnight. Took an extra 30 minutes before someone came to my rescue. Thnx

Nice hotel with good accommodation even tho there is no in-person staff. Worst part is that the walls are thin and you can hear every noise from the city to the neighboring room. They provide earplugs but I cant sleep with those in.

I’ve stayed at sonders in Brooklyn NY and did not like my stay at all but loved my stay at this location very clean and comfortable all the amenities that I needed were included! Great location as well a walk away from food, shopping, transportation and groceries. Only thing is the floor to ceiling windows on the first floor should have curtains/blinds but other than that I really enjoyed my stay. Would book this place again
