Hotel is beautiful when you walk in. There is a smell when you first walk in. The rooms themselves are in dire need of being updated. Carpet is old and frayed. Furniture is old and plenty of dust everywhere. You can't open your door because there are so many little bugs.. in which they tell you about. Don't worry, they're not bed bugs and they won't hurt you. But they are thousands of them. The bed was comfortable. The bathroom vanity was nice with plenty of room. No microwave in the room itself. I would give the rating an average.
