Bay Village

10/10 Excellent

I cannot say enough good things about our stay at the Four Seasons in Boston. It was clean, amenities were great, and the staff was friendly and very resourceful. A special thank you to the Hotel Manager, Christopher Werth and his staff as they made sure our stay was perfect. Not only were we upgraded from Executive Suite to Presidential Suite, we were even offered to refrigerate our left over food so we could enjoy our last day in the city worry free as we had already checked out of the hotel....
