Good: location, very clean rooms, impressive lobby albeit "The Shining-esque" which I liked, staff will accommodate basic responsibilities, some with attitude, some, with lovely energy. The lovely staff stand out, the others...eh, forget them.
Bad: it's the small things that add up: key not activating gym, or room post gym, steam room not working (the reason i chose this hotel over the Embassy Suites with the breakfast option..which will cost you $20 out of pocket), poor, minimal food choices, expensive...let it go traveller, have a good sleep in your clean bed, catch your flight.
Ugly: when the menu asks to inform of allergies, and I, the gluten free customer do, do not dismiss me, nor make zero attempt to accommodate my simple request (baked potato) ...gluten free foods can be easy for your chef, even if you dont understand the need...and for me, the person with the allergy, I'd tip you even bigger for actual service rendered versus dismissing me as a customer from your own ignorance and arrogance.

The Logan Airport Hilton represent reasonable value for money.

The Positives
1) The hotel is attached to the airport although the walk can be a long one depending on the desired terminal. A shuttle service runs every 15 minutes via the various terminals and the Boston 'T'.
2) The hotel was representative of the Hilton standard in terms of its infrastructure and front desk service.
3) The gym was excellent.

The Negatives
1) The one restaurant option, apart from using the airport options, was expensive and the service and food were average. A hamburger cost $16 and it was not worth the price. Service was marginally slow and somewhat contrived.

The In-between
1) "Joey" was one of the shuttle drivers. He was exceptionally enthusiastic and even offered donuts and chocolates as a courtesy. impressive. Unfortunately, his enthusiasm often manifested in him interrupting CONSTANTLY. it was difficult to maintain a conversation with him. That said, he is memorable.

This is an average Hilton property. Convenient to airport (you can walk to terminals), but not really focused on an excellent experience. This lack of focus is evident from the service in the restaurant (four meals and only one had good service) and from attention to details like a noisy ventilation system in the room.

We have stayed here once in the past and have stayed in the Hyatt also located at the airport, and after staying at the Hilton again, we would recommend the Hyatt, which has a free shuttle, though you can't walk to it.

For this visit we selected the HIlton because we had a business meeting at the hotel and Hyatt provided a cost for meeting facilities much more expensive than the Hilton, so if that is your need and cost is an issue, check out the Hilton. The staff did efficiently and satisfactorily handle all meeting related tasks.

I'm traveling through Boston regularly. When I'm in need of a place at the airport, I usually pick my choice between either the Hilton at the airport or the Embassy Suites. Price is my deciding factor as both properties can fluctuate wildly, at any one time, one or the other can be more expensive by over $100.
What I like about this property is that it's so easy to get to your flight in the morning as it's just a simple walk.
