4-star hotel with comfort
We just stayed at this hotel for four nights during our Boston trip. We really enjoyed our room (king size bed) on the 4th floor. We booked the hotel through Priceline and got this hotel selected based on the bidding process, so we got an amazing deal for a high-quality hotel. 
It was located just a couple blocks away from Boylston which is a main street running East-West in the Back Bay. It was a short 3-5 minute walk to get to the Arlington Green Line T-stop and even closer walk to the Back Bay Orange Line T-stop (2 mins). 
The hotel main area is nice and matches its "four star" rating. Our room was a good size for just us two and the bathroom was clean and an appropriate size for the room. It's nice that the room includes a small mini-fridge with a couple complimentary bottles of water (which they re-stock and bring more if you request it!). The bed linens and towels are nice and clean.
