Fantastic!
This was my first stay at the Lenox hotel and it was a really fantastic experience - they truely deliver great service! The whole team is really helpful and friendly. Just one example was when I hired a car for a day trip , Kristie, the concierge arranged a bag of snacks for my journey, a lovely touch!
The hotel is in the Back Bay area, close to Newbury Street which is lovely, lined with restaurants and good shopping. 
I would highly recommend this hotel to any traveller to Boston.
