Disappointing small, dark rooms and hit and miss service
Had quite a disappointing 6-night stay at this Fairmont property and would probably not recommend this hotel to anyone looking for a smooth, enjoyable 5* experience. 
Although staff seemed generally well intentioned, there were way too many hiccups in the service during my stay. For example packages that had been delivered took an awful long time and repeated prompting on my part to be located and delivered to my room. Moreover, I caught the gentleman cleaning my room throwing receipts away in the trash I had left on my desk.
The most disappointing aspect of my stay was/were the room(s) assigned to me. Upon check-in I found dirty towels on the bathroom floor and a view from my window on a wall. After complaining about this I was assigned a new room (see attached pictures), which was even darker with a view on and constant noise of ventilation pipes. Apart from this, I found the rooms of the hotel really dark and smaller than any room I had stayed in before at a luxury hotel. Being too tired from my flight from Europe however, I decided not to further complain and ask for yet another room. 
The newly renovated lobby does look impressive but based on my experience I will not stay at this hotel again during my next visit to Boston.
