We love having the bottled water on each floor. Music each time we stay. There was an issue with our bed. We will address that with the appropriate people

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
