The Eliot is one of those classic hotels that you can't help but love. I had a King Suite and it was huge, with a large living room / office with french doors closing off the bedroom / bath area. I had assumed that the rooms would be small, and was pleasantly surprised at the size. The bathroom was averagely sized but nicely appointed with a cool and odd half glass wall partition shower.
Dining options are obviously immense, being in the Back Bay. Right downstairs in the hotel are Clio and Uni, which are both Ken Oringer restaurants and some of the best dining in Boston. Clio's bar is legendary, and if you're a sashimi fan (no maki rolls or sushi), you must eat at Uni. It's amazing.
Service at the hotel was great. Always somebody there to open the door, call a cab, valet your car, stash your keys, get the elevator. Just old school service and vibe.
Would most definitely stay there again.
