I was in town for a wedding and stayed one night before catching a 5:50am Amtrak train back to Boston. The studio I had was large and had a kitchenette (had a range which I didn't use plus dishwasher, full fridge), comfortable king size bed with numerous comfortable pillows, and clean bathroom. Free wifi.
Besides bringing me to the train station, the hotel shuttle also picked me up from the BWI rental car center that night (so I wouldn't have to deal with returning the car the next morning).
Overall, a great stay!
