We just completed a two-night stay here for the weekend. DH is a Diamond and used 2 weekend night vouchers we had through the HH Citi card. Front desk was nice at check in, but didn't upgrade us. We were given a city view room which had a horrible view of the parking deck. There is a lounge on the first floor which is stocked with a variety of beverages (non-alcoholic), and the lounge has a separate entrance to the main breakfast buffet which was fine.

Our stay overall was actually quite disappointing. Little details about this hotel just didn't sit well for us. After the first night, housekeeping didn't service our room until late in the afternoon and didn't empty the trash or remove plates and coffee mugs that we had brought up from breakfast. Second, the bed (not the mattress), but the bed wasn't bolted properly to the wall. When the two of us sat down on the edge of the bed to put on our shoes, the entire bed almost flipped up. The lounge ran out of hot water and things never seemed to be completely cleaned up all the way. Little details like this really turned us off. I think this is one of the more disappointing stays we have had at a Hilton in a while. I think if I were to come back to Burlington, I may be tempted to check out the HGI down the street.

Edited to add: The hotel charges $15/day for parking to everyone because they have their parking in a City-owned garage. This didn't bother us, but something others may want to be aware of.
