Pros: Unit is as advertised, and it's all to yourself, which is great. It's not walking distance to anywhere, but it's really close to 315 N/S, Arena District, Campus, Downtown, etc., so it's great. Parking on premises isn't secured, but having that available to us was really key for our visit. Towels and linens were clean, water was hot, AC was cold, and the shower curtain looked brand new, so no complaints there! Water filter was really nice too.
Cons: Messaged the host about the shower not draining, and maintenance crews were supposed to come by two of the days we were staying but no one came. Some strange lapses in communication (3-4 bags of paper towels and forks dumped in front of the door without any warning or message was one that came to mind) and the parking not being secured might be some things to consider (though we never felt like our car was in danger of being broken into).
Mehs: These are a few nitpicky things. Furnishings are pretty basic -- the furniture is serviceable. However, in the kitchen, don't expect to be able to cook for yourselves beyond some really basic meals, if that. The rest of the apartment complex is inhabited by a relatively young crowd, and while we were never woken up by noise or partying, the noise did carry into the living room one of the nights we stayed there.
Overall, it's a nice, affordable, and comfortable place all to yourself to stay for a few nights in Columbus.
