Inner Harbor gem
We went for the "Sailabration" tall ships extravaganza over the June 16-17 weekend. We got a harbor view room on the 10th floor which proved to be a ringside seat for watching much of the festivities. The lobby and entire hotel was very clean and stayed that way despite the throngs of people that were staying there. Our room was spacious, clean and very comfortable. The bed was great for my wife (she prefers a very firm mattress), a little firm for me, but still very comfortable.
 The staff was friendly and despite the crush of people, they were very efficient and patient in handling room assignments and answering questions about the events going on. We arrived fairly early on Saturday morning (I was hoping for a lucky empty room as we had an early lunch engagement) and our receptionist diligently tried to fulfill our early check-in request, but no luck. Left our bags and went sightseeing. They dutifully called when our room was ready, and we were thrilled with the view and overall excellent amenities of the room. I really like the Aveda shampoo! 
 The great view of the Inner Harbor and the proximity to all the Inner Harbor activities is a real plus. We could leave the car and walk easily to anything (National Aquarium, restaurants, Constellation, et. al.) We were able to watch the Blue Angels show from our room and had a great view...especially excellent as all the other venues were packed and some pretty much inaccessible.
 The workout area isn't huge but there were four or so of each: ellipticals, treadmills, stationary bikes. Enough weight machines for an effective workout. Superior to most hotel fitness areas. Once again, it was clean and with a pleasant attendant.
 The downsides were the elevators being so crowded and slow, and the room was noisy from exterior sounds of the Harbor festivities. Once the activities were over, the room was quiet and we both slept well. So I think you can attribute the minuses to the very high activity level of the special weekend.
 Overall, this an excellent hotel for Inner Harbor activities or a football or baseball game as everything is easily walkable. Clean, luxurious and friendly are keys to a great place to stay and the Renaissance delivers.
