We had numerous issues. First, we were given a room close to the desk on the first floor. Our window looked out onto the parking lot. I was never able to open the blinds because there were cars and people constantly moving in and out of the hotel, so our room stayed dark and unpleasant. I tried to upgrade, and was willing to pay any fee, but I was rudely told I could not change rooms since I booked through a third party. This has never prevented me from changing rooms or upgrading, ever. I then had issues with basic supplies. The coffee pot was terribly dirty and unusable. There was no shampoo, conditioner, and no body wash in the shower. I discovered this while showering - totally inconvenient. I called the front desk and was told these items were on back order. I asked why no one informed me of this when I checked in, for which the front desk had no response. I had to use hand soap for shampoo that resulted in a rash on my forehead. Lastly, the front desk person was incredibly rude to multiple people. I witnessed her speak rudely and sharply to many guests, unnecessarily, not just me. Over the years, I have stayed in Hiltons across the country and across the globe. I have never, ever experienced such poor service at any Hilton nor at any other hotel. I expect Hilton to do better. I will not return here.
