Absolutely amazing value. The apartment was super clean, tons of space in the living room and kitchen, and the hosts were very responsive to any questions. The kitchen has everything you need if you'd rather cook in than eat out. They even have a french press and coffee grinder in addition to the regular coffee pot!
It is mentioned in the description that the place can be a little chilly at first, but I would not let this be a deterrent. It was snowing when we were there, my girlfriend and her mother are always cold, and this was not remotely an issue. The fireplace warms things up very quickly and it was never that cold, even for a pair who are perpetually cold.
The apartment was 10 - 15 minutes from everywhere we needed to be while in Columbus, including the convention center, and I will look for this place first the next time we are in the area.
