Great location
I was here for a conference over the course of four days. My husband joined me for part of the trip and we got to see a couple of games at Camden and explore Baltimore a bit. Overall, we had a good experience at this hotel, and would stay again.
The good:
1. The location is amazing - especially if you are a baseball fan. The hotel is about 100 feet from Camden yards, the Geppi museum, Camden yards hall of fame museum and about three blocks from the birthplace of Babe Ruth. The hotel is about a half mile to mile walk North to Mt. Vernon where you can see the Peabody library, Friedberg Hall and the Walters Museum. If you walk about half a mile to a mile East, you are right in the middle of Little Italy with lots of great dining (Capriccio...amazing)
2. The service was consistent and friendly. The front desk staff, valets, housekeeping, bellman, bartenders and restaurant staff were consistently nice. 
WARNING: The Diamond Tap gets swamped before and after Orioles games. We are baseball fans and were ready for this, but if you are not "into" dealing with obnoxious seamheads, then this will annoy you. We went to the games on Friday and Saturday nights, and actually had more success with post-game dining at the Hotel Lobby bar. The staff really does do their best to accommodate people during this busy time. 
3. From a conference perspective, it was fine. The signage was appropriate without being obnoxious and if I had questions people were helpful in pointing me in the right direction. The rooms were kind of chilly, but the conference was during a heat wave when it was 105 degrees in Baltimore, so they were probably overcompensating a bit.
4. The food in the "Lobby Bar" was a nice surprise! My husband had a flatbread pizza and I had a charcuterie/cheese plate with fresh fruit. These were tremendous values, especially for hotel dining. The bartenders were great.
The "o.k."
1. The room was fine. The bath products were fine (my husband used them.)There was no minibar, but they did have a decent late night room service menu. I mean, overall the room was totally serviceable and fine, but nothing really stood out. 
The "I don't know"
We didn't use the hotel Wi-Fi, business center, fitness center, parking and I have no idea if there is a pool or spa. 
Overall, we would stay here again simply because the location is so ideally suited to Orioles games and exploring Baltimore - either on foot or cable car.
