Great anniversary weekend!
This hotel is walking distance from everywhere. On Fri and Sat there is a farmers market set up literally out the front door and around the block. I loved shopping and dropping stuff off in our room. We were literally in and out of the hotel all day. Very convenient! 
The rooms are beautiful. I enjoyed the mirror makeup area because there's a little roll out ottoman stool type thing and the lights are dimmer than the bathroom. I also like that the standard room has a balcony. The bed is very comfy. The only things I thought were bad is the tv was grainy and wifi was not free. But it was a blessing for us because we wanted to be out walking around and not getting distracted with that stuff. Everything you need to know, you can ask someone in Boston, whether at the hotel or at a pub. It's a great place with nice people.
The staff was amazing. The nicest and most helpful was Daniela but all, from front dest to doorman were great. On a somewhat unrelated note, I must suggest women leave their heels at home. It just doesn't work in Boston.
