The hotel overall is beautiful, front staff is amazing. The deli had food made to perfection. However, the sirens at night are horrible, but I understand being in the City, this is expected. The very VERY worst part, is the maid will wake you up at 8 am to clean your room, even though check out is 11am.

Almost all of the staff went above and beyond. A security guard saw that we were lost and went out of their way to help us, the cleaning staff always greeted us with a friendly good morning, and the staff at the bar and little market were courteous and also above and beyond helpful. Unfortunately we had the same front desk person for check in and check out and I was surprised by their gruffness, and it was disappointing to start and end on a not so positive note.Perhaps they were irritated by the busyness from the conference. :/ The room was clean, with comfy beds, and plenty of towels. It was disappointing there was no literature about the hotel (maps, restaurants, check in/out time, room service etc.). There was a tablet in the room that likely had this information, but it was broken.

The room had several aspects that were damaged. The bathroom had a broken frame on the cabinets that fell off, the couch cushion had a hole, etc. I paid over $275 for the room (including parking), I didn't feel like the quality of the stay matched my bill.
