I had a corner room and stayed just one night between arriving at Logan Airport at midnight and leaving again the next morning. While the bed was comfortable, the air handling system was noisy and kept me awake. And the room was cold. I was tempted to try to turn the temperature up, but afraid I would just add to the frequency of the system cycling on and off, which noise was keeping me awake. In the morning, the breakfast area was also cold, causing my eggs to become cold before I could eat them.
On the plus side, the shuttle service to and from the airport terminals was responsive and friendly. Kudos to them.
