All staff were amazing, very helpful and friendly. The hotel was great no fault of anyone but the restaurant and bar was closed all weekend so difficult to give top marks as a review as we paid full price for incomplete facilities. From our limited experience we could stay again but cant give full review as didnt recieve full experience.

Nice enough place to stop when driving long days. Pricey for what it is but clean, somewhat renovated. A/C could work better. Restaurant was good but too expensive. Limited choices on this route.

This hotel was perfect for my stay as it was 4 minutes to work each day while on business. My only complaint is it is an industrial area, so nothing to do, the resturaunt and bar within the hotel are closed Friday, Saturday and Sunday other then for breakfast.

Too expensive

Staying here many times. The hotel is pretty good but I feel it’s. Now very overpriced and does not offer value for money. Other hotels in the area are half the price, not quite as nice but a lot cheaper

hmmm…

they have a locking gate for cars to pass that requires a phone call to have unlocked after day time hours , and can take long time for someone to pick up. Room key needs re programming nearly every second time used - needs an overhaul Don’t count on decent desk for computer work…

We used this hotel for a stop along the highway during a long road trip. It is a fine, basic, no frills hotel. Easy parking, although it did not look like the safest area. We arrived late. The staff was helpful. There is a bar/restaurant on site but we did not use it. They also have drinks/snacks for sale near the front desk which is a nice to have.
