My stay was very comfortable but there was a few things that I was unsatisfied with. So I travel alot for work and never have I ever had to pay $50 a night for parking, that was a little insane to me. Also I had requested a room with a tub and I got one with a shower and ontop of that, every time I went to take a shower, there were some kind of knats or fruit flys coming out of the drain so that was definitely an ick. And lastly for a hotel that charges a lot of money to stay there, there should not be rammy teenage boys running around the hotel floors all hours of the day and night and slamming doors. I had to put on my white noise machine just to drown them out so I could sleep. But other than that it was fine.

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
