Unfortunately some things were falling apart in the bathroom The shower floors were super slippery when wet the material felt really unsafe so be careful while showering The size of the bathtub makes no sense And the first day I woke up to construction going on on my floor so didn't get to sleep In. Overall great location and nice spot Super convenient bag drop off for the day

Great location in a lively area. Close to Rogers Centre and even closer to the theaters. The clean lines and modern design and furniture were great. Lots of storage for our clothes and personal items. The bathroom door needed a doorstop to allow steam to dissipate. Also, some attention to post renovation clean up required (drywall mud on window sills and ceiling by window). Attention to detail on this build was otherwise amazing. Kudos. I would recommend this hotel if you're looking for clean, modern and don't need in-hotel amenities. In this area there are so many dining and drinking options.

Cost-effective option in highly sought after area

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).

Good quality for the price point, ideal location. Key card on the phone often took multiple tries before it worked, and toilet pressure was next to nothing. Other than that, good spot! Will likely stay again,

The room was quite nice, other than the bathroom - I did feel like it needed a deep clean, some fixtures showed wear and tear. The tub is huge (very deep) however the shower was barely a dribble - no pressure at all. The real problem I had was with the customer service. I made a mistake when I booked the room (wrong location) and asked (pleaded) if I could cancel - this was months in advance. I was refused. I understand that I did book a non-refundable room, however it was an honest mistake, again months in advance of the booking, there could have been some flexibility. Fast forward to the day of the booking, I was charged again, for the full room. I contacted the hotel and was told I had to contact Expedia - even after I explained I had fully paid for the room - they should not have charged my card that they took for the deposit! Again unwilling to help - Expedia was able to help and got the mess sorted very quickly for me. Overall the room was fine, service was not - and for the price I would have expected more.

Great, centrally located property. A few small glitches, including no garbage pail or hairdryer in the room. Then a big glitch, overhead flooding in the bathroom requiring I changed rooms 😱 however everything was handled quickly and seamlessly by the gracious staff.

It was really convenient to have coded entry. The area felt safe and had lots going on. The room was small though and I found it odd that the entire bathroom was just frosted glass. Would be okay if it was a single or a couple staying but probably not ideal for friends. Had a slight issue with the tub on the last morning but I used the app chat function and they were very friendly and responsive.

There was no hot water in our room, after coming back at 10:30 pm when all we wanted to do was shower and go to bed, we waited over an hour for someone to come after being told 20 minutes. I was given different directions and confirmations than what was actually provided, no one on site.

Location was close to certain to harbor, walking 20 minutes ti museums. Grocery and Starbucks close. It’s a noisy area, construction going on..air conditioning didn’t work for a few days and difficult to use AC controls. Showers have no doors, toilet doors hard to open. The manager was very kind and helpful and worked with us to try to make our stay more comfortable.

Bathroom door was way too heavy. I’m a big guy, so I could not imagine how someone elderly or disabled would get into the bathroom. Shower curtain didn’t cover the whole shower, bathroom floor got soaked. Received messages from the hotel in the middle of the night making it hard to sleep. Windows did nothing to curb the noise. Had to check multiple times that there wasn’t an open window to explain the amount of noise in the room.

Very clean and convenient accommodation. The communication with the staffs was a bit difficult since there were not any staffs staying and no reception there. They offer the online 24/7 communication, but seems like those online staffs are not familiar with the neighborhood, so that they gave us wrong informations several times. No-contact check in / out was convenient, but we felt unsafe to type the passcode at the entrance of the building which located to the public road and probably people behind us could see the code. Same code was used for the opening the door at our unit, so means if someone want to sneak into the unit, it would be possible. That process supposed to be cut off if I could use the Bluetooth of my phone, and the App said it’s set up perfectly, but unfortunately the Bluetooth system didn’t work. Hope they’ll improve their system.
