The hotel website is raising wrong expectations by communicating "boutique hotel" - at least for European standards. The hotel was just renovated (paint, carpets, furniture etc.) and has thus a modern looking interior. However, the rooms are still what you typically get in a city hotel. What you should know in my opinion:
Hotel exterior is still being renovated (some rooms apparently smell because of the fresh paint)
There is a club in the hotel; try to get a room on a higher floor or you will not sleep
Bathrooms were updated but showers etc. are not new
Standard and deluxe rooms are small, it is worth spending the extra money to get a better room
The team was very helpful and friendly
The location is great to explore Boston - just step out and you are close to everything
