Tired
Admittedly, I was tired during my visit to Baltimore, but sadly so was this hotel. Rooms dark with no overhead lights; dingy decor: I think trying to me subtle, but it was actually rather dreary. This was not helped by the fact that both blinds in my room had worn out mechanisms, and so didn't open. So, there was no daylight either. A pity, as I would have had quite a nice view of the cathedral spire. The carpet was very tired, very olive and mud coloured to the extent that it looked as though it had not been cleaned for some time, although I am sure it had. Bed was OK (very firm - be warned if you need a soft mattress!), bathroom OK, although the water pressure in the shower was way below what I expect and am used to in American hotels. Overall it was clean and well serviced although there were no tea bags in my room on arrival (shock horror for an English traveller!) and those supplied were ghastly! And only powdered coffee creamer, no milk. 
And, as others have said, lots of steps.
Positives: it is in a great location. Mount Vernon is a really interesting part of Baltimore, lots going on, very pleasant to wander. It feels like a safe area, and is central and easy as a base. And Gene in the restaurant was really friendly, helpful, charming and cheering.
