Almost Perfect with Some Minor Tweaking
This is a grand corporate hotel. It has a lovely, airy spacious lobby, a nice gym,
Indoor lap pool, great little gift shop. The room we had overlooked the airport terminal and it was beautiful with it's large picture window. There was absolutely no airport noise. The bed was very comfortable, the bathroom fine and very clean. Shuttle service was terrific and the driver extremely helpful.
Caveats:
Unfortunately, the breakfast in the hotel restaurant was a big disappointment and very expensive. The server couldn't have cared less. We had to ask for napkins, water, more water...She goofed our orders up and never came back to ask how the food was. When she finally appeared, we had given up and I simply asked for some butter for my toast. She informed me my toast already had butter on it. Two egg breakfasts, 2 coffees ($5 each) cost $45 before tip. Advice: Do not eat in the hotel. 
Second, the housekeeping staff starts work around 7 am and you will know it because they converse loudly with each other in the hallway outside your door. Even if they aren't nearby, you can still hear them because the are loud and the noise carries. I think management needs to address this as it went on all morning.
This hotel is my second choice at Logan airport after the Hyatt. The staff at the Hyatt is much better and seems more attentive to guests.
