A cute little historically protected area over on the East side, just north of the Miami river.
I don't know much about it, but I liked the mood of the area as I explored.
If you like to walk and peoplewatch then downtown Cincinnati is a good place to start. Not only will you see many different kinds of people but you can see some good victorian architecture.
Eden park is a beautiful park set next to the Mt Adams neighborhood of Cincinnati. It is a great place to spend time walking solo or with friends.
I found the American way of building house quite bizar. I thought these houses were only built for western movies in the spaghetti-westerns from the 70´s. However, they look very nice.
