Lovely hotel. All amenities were given and room was very clean. Walls are a little thin so you can hear your fellow guests nearby and above you. Only caveat was that the fridge was not working but overall it was a great place to stay! Front desk was very helpful and always had a smile and greeted when we were in the lobby.

Check in experience was less than acceptable. When you have a busy Saturday night do not staff your front desk and engineering department with unknowledgeable staff. We were told, and verified by the engineer, that the room had a sofa, it did not. My son had to rent another room instead of being able to sleep on said sofa. We had to spend an additional $200 for that room. Very disappointing.
