Whenever I travel, I typically seek out a hotel within the Hilton family and, although my stay was not in my preferred city, this HGI location was remote; but, pleasant. The lobby was appealing; but, the snack bar was nearly empty from what I could see at the front desk. The clerk never announced our room number; so, I had to check the key folder. There was something on the floor in the walkway to/from the elevators that was never removed or cleaned during our 3-night stay. The hallway of my floor stayed cold and noisy although the temperature outside was in the upper 30s. I had an extremely hard time using my room key to open the door. When we first entered, the A/C was on, set at 70 and loud. I managed to switch it to heat; but, it took a full day to cool down. However, it was never warm in the room and there was only one blanket to use. I thought about bringing it up; but, I thought things would improve - which they did not. It was so noisy. Since we had food to store in the fridge, I had to adjust the thermostat which created a loud piercing sound. It also never reached optimum temp. The pillows were really soft; but, I needed them to be firmer to prop up. And even though we self parked, we were at risk of being towed if we didn’t put a green piece of paper on our car’s dashboard. I disagree with that - a new first.
