"Great Front Desk Service"

10.0

I have always enjoyed my stays at the Triton over many years of business travel from the east coast. In this case I booked a stay for my husband and there was a billing issue around upfront fees that we’d paid to Expedia that were not transferring through to the hotel. This is a shout out to Tony at the front desk who was patient and resourceful, diligently working to resolve the issue for us and then following up later to confirm. Thanks, Tony!

no hubo nada que me gustara más

La habitación era pequeña, reservé 2 habitaciones cada una para 2 personas, una de las habitaciones la solicité con dos camas individuales, pero me dieron una sola cama y querían cobrar adicional las 2 camas

"Breath of fresh air."

10.0

I had booked a room in another hotel that wasn’t up to acceptable standards. Managed to get into Hotel Triton. What a relief. My wife has stayed other times and enjoyed her visits. I soon discovered why. Lovely experience at every turn.

"Kind and helpful front desk"

10.0

HUGE thank-you to the front desk team here. I had a bad travel morning: my luggage-storage booking elsewhere completely fell through, and I found myself carrying all my bags around with a four-hour tour ahead and nowhere to put them. I stopped in to ask for help. Even though I wasn't staying at the Hotel Triton and there was no obligation to do anything, Jay A. and Jay C. were so incredibly kind and took the time to help me out, and I was still able to catch the tour afterwards! It honestly turned my awful morning into a silver linings story, and now I know where to stay next time I'm in the area :)

"Very Bad experience"

2.0

Bad experience. I initially booked from 9th to 13th June but had to check out at 12th. I got charged for the 12 th night as well. Bad room had some kind of smell throughout. Do not recommend anyone.

"Great location and staff!!!"

8.0

I liked the location and staff the most. Staff went out of their way to make our stay as enjoyable as possible. The location is awesome because it is very close to everything downtown.

This is obviously nothing they can change, but rooms and bathroom are tiny. Just plan accordingly.

"Had a wonderful time."

10.0

Walking distance to nice spots in downtown. Cozy hotel atmosphere overall. Comfy rooms cleaned every two days. Noise from outside the building nicely isolated, although noise from outside the room can be heard at times. Wonderful service and helpful staff. Rey helps me a lot helping with my checkout extension. Coffees and light breakfast to simply start the day. Good value for my stay overall.
