It was going well until....
I spent there the night of my birthday. 
The hotel was in an excellent location, it's in walking distance to the Boston Common building and the park. The room was cosy and the bed super comfy. I was extremely happy as I was travelling from Chicago to Boston and I honestly wanted to relax in a nice hotel. I checked out the following morning regenerated and ready to face my whales watching tour that I planned for my birthday... 
the disappointing about the Back Bay experience was simply that my partner from England got in touch with the Back Bay Hotel to deliver me a birthday message with a surprise (a room service) for my birthday that I simply didn't get... and finally I had to handle my disappointed partner who was expecting a thank you message or something... for the surprise... Honestly... Birthday was simply spoiled because of the inefficiency of the Back Bay hotel concierge. PS. They had my details as well and I was honestly hoping for an apology... which of course I never received. Sorry guys, this is definitely not 5 or 4 stars service to me!
Do you have swimming pool and SPA? Lol If I only was told about it when I checked in... I might have been able to rate it!
