Fin was a cool dude and fun to do business with. The apartment was conveniently located in Columbus' friendly SoHud neighborhood, just northeast of campus. I never had trouble finding free street parking.
I subtracted one star because of some inaccuracies in the listing, and another because Fin's dog big me.
The description "Entire home - You’ll have the apartment to yourself" is debatable. The room is the attic of a duplex apartment Fin owns. The attic is equipped with a toilet, shower, refrigerator, and sinks. Amenities from the listing (washer, dryer, stove) were in shared spaces downstairs.
The room does not have a "separate street or building entrance" as the listing says. To be fair, Fin gave me a key to a separate side-door that only I could unlock, but I still had to walk past other peoples' bedrooms, kitchens, and showers to get to my room. The street address was for the wrong side of the duplex.
The lack of a separate entrance became a safety issue when Fin's very large dog bit me clear out of the blue as I was leaving one day. After a few days Fin moved his dog somewhere else. I would recommend that guests with small children or pets ask Fin to keep his dog somewhere else during their visit.
