Nils's place is a tidy studio apartment and exceeded all of my needs. It is located at the south end of the Short North region of Columbus and is therefore close to plenty of bars and restaurants. I was in town for a conference at the Greater Columbus Convention Center. Nils's apartment is roughly a five minute walk from the convention center, which made it extremely convenient. Free on-street parking is not particularly close (10+ minute walk), but is available.
I would highly recommend this apartment for anyone attending a convention in Columbus or for a weekend of Columbus nightlife.
