Nice hotel close to Camden Yards
We stayed at the Hilton for 3 nights in September and were very pleased with our stay. We happened to be there when the Orioles were out of town so the area was quieter than I'm guessing it is when they are in town. It's directly next to Camden Yards though, which means there's lots of sports bars in the area (helpful for watching college football games!). The hotel is also about a 10 minute walk to the Inner Harbor, with several restaurants on the way. There is also a free bus that has several routes around the city and there is a stop right outside the lobby.
We had a harbor view room, which was beautiful (don't expect the harbor to be your total view, there are other buildings in Baltimore that block a portion of it). The room was very clean and spacious and the bed was extremely comfortable. Service at the hotel was also great, friendly and helpful staff. Our only issue was that they double-charged us for parking but realized their mistake immediately and resolved the issue as soon as they could. While parking might seem expensive at $28/day, it was in line with every other hotel in the area and we had in/out privileges and had no issues with finding a spot. The bar was a little pricey but the drinks were strong and the bartender friendly.
