Stay far far away!
We had a room booked for $89, when I called national Marriott to confirm the rate the night before, somebody had overriden the rate to $179. National Marriott didnt even understand how the rate was so high and they changed it. This should of been a sign not to stay here.
We had just visited a local University, and arrived at the hotel. We didnt even walk in the front door, let alone the parking lot. It is an awful area, by far one of the worst areas I have ever seen. There are bums on the street and people just hanging out on the streets. There is low income housing right across the way from the hotel.
My advice; for safety, pick somewhere else, we did the Hampton Inn White Marsh and what a great place.

This hotel was a little outside of downtown Baltimore, but it was quite nice. The rooms were clean, breakfast was decent, and the staff was mostly helpful. They didn't go out of their way to help us, but they weren't bad either. It's not in what I would call the greatest area, but it is in a city, so I guess it's to be expected.
The walls were sound proof, as we didn't hear any noise during our whole stay (4 nights). The beds could've been more comfortable, but you can't have everything!
