Beautiful old hotel, pricey, very small rooms
The Westin is really a beautiful building in downtown Columbus, and it was quite convenient in terms of location. However, the prices are quite inflated ($199/night) considering the size of the rooms, in my opinion. The beds and bedding are lovely, the staff was quite friendly, and the room service was good as well. I forgot hair spray, and the hotel was kind enough to send someone to my room with a couple of small bottles, which I appreciated. 
Overall, I would recommend the hotel if you're in town for a quick trip like I was, but definitely can't imagine staying in this hotel for any longer than a night or two because of how cramped the room was.
