Frank's place was excellent. It was very clean and well maintained. Everything worked out exactly as expected. There were no issues with the place what-so-ever. We were just in town for a show and the apartment was perfectly located with access to places to eat, as well as the subway.
It was pouring rain when arriving which made the place a little difficult to find initially, but in fair weather, it would be not a problem.
I recommend Frank's place for either a single business person or a couple visiting the city.
