A great military hotel!
While this hotel does not cater only to military members and their families, it certainly does a terrific job of supporting those who do take advantage of the low rates and great location.
We stayed for a weekend in September and were pleasantly surprised to pay a rate of just shy of $100. On a busy Boston weekend, that was a steal. Our room was fine. It could certainly use some updating, but the bed was big and not terribly uncomfortable. Our room came with a small table and two chairs, nightstands, a dresser, and a desk. We additionally had a fridge, oven, stove, microwave, and coffee maker, though there were no pots or pans to use.
I've read in some reviews that there's no A/C. This was not the case for us. In fact, I thought it got too cold at times. The temperature is easily controlled, and the view from the windows, while not spectacular, is private.
The staff at the hotel were extremely nice and helpful. They seemed genuinely interested in making sure our stay was comfortable.
The location is fantastic. It's safe, near some good restaurants and great historical landmarks, and just a ten minute walk from the water ferry (which is free for active duty military members and their families). At night, we found the hotel quiet, which is good for those who, like me, have trouble sleeping.
Another benefit is that it's attached to a YMCA, which means you can use the facilities whenever they're open, including a gym and a pool.
The only negatives about the hotel were that our room was not cleaned the second night (though I did have the do not disturb out until 9:45am), and the elevator can, at times, take a significantly long time to get to your floor. There are stairs, but it's six stories tall. Also, there isn't any parking during the week. You have to use a garage down the street, which is a bit of a walk with suitcases and uniform bags. On the weekends, you can park on the street.
Overall, this was a great stay and we would definitely choose the Constitution Inn for our next Boston visit!
