The Marriott Cincinnati North is a nice hotel overall. The 8th floor lounge is really nice and a great place to relax and meet others. The staff is very, very friendly. There is a starbucks and a restaurant near the lobby.
The only issues I saw were a few cleanliness issues. When you come into a room you don't want to see remnants of the person before you. They would have to really improve their cleaning if they want more stars from me!
