Hotel was mostly fine. Could hear lots of noise outside the room through the door and walls. Was very expensive for the level of quality but it was a holiday weekend.

What a gem in Boston! I've been to Boston many times and usually stay closer to the Downtown Crossing area. This time we stayed at the Whitney, choosing to try out that part of town. We loved it! Bigger than a boutique hotel, but small enough to feel intimate. Charles St is a great walking street, and we loved the location. The room was on the ground level (actually partly below ground) but was excellent! Well-appointed room, a good amount of space for Boston, and super professional staff. I'll be back when I come back to Boston
