We had a wonderful stay at Alexander's property. I have stayed in several airbnb over the years and Alexander has to be one of the top communicators that I have ever worked with. He is quick to respond and is willing to take care of issues that arise. We only had two minor issues that came up like a smoke alarm that needed a new battery and a door that needed a couple new screws. Each was taken care of within the hour.
The only hesitations I would offer for would be people staying is that this is unit is not a detached home. So there were other tenants in the building and the walls were a bit thin. This is also on the edge between a really nice area and one that isn't so nice. We had no issues whatsoever but were a bit concerned driving in.
Overall, if you are looking to stay in Columbus or the surrounding area I would highly recommend this place and especially Alexander in general.
