Cute and trendy hotwl but there was a loud party on-site which ruined experience. It felt clean but our mini fridge had takeout left from former guest, so maid service obviously missed that.

This place gets 3 stars from me only due to its great location. It's in rather poor repair and its overall appearance and upkeep do not reflect well on the Hilton brand. It seems clear that property ownership are not bothering to put money into it because they know they will get traffic from the airport.
