I had a great stay here, from the clean rooms, great customer service and care.The king bed and pillows were comfortable. Room was cold. My first time staying In a room with bathroom in the hall and it wasn’t bad at all. Bathrooms were always clean and I never had to wait once for the shower. They offered umbrellas for the guest, it had been raining all day. They have a gym and a restaurant connected to the hotel which was nice because I ordered online for pick up and i didn’t have to go far. They do also have a coffee shop downstairs! Overall, I would definitely stay here again on my next trip to Boston!

Stayed for a few days here. Stephanie and team are fantastic. They went above and beyond to care for our furry travel companion (Gatsby) to ensure he felt good. Gatsby was treated like royalty with in room dining menu specially tailored for the furry ones. It’s the best place to stay in Boston without a doubt. If not for the location and history attached to it, definitely for the team that takes care of the guest with care and a touch of humanity. Very well done people. Hats off.

Bed was uncomfortable (both mattress and bedding). The light across the street was on the whole night. A/C didn’t work, and towels were small and dry.

We had a wonderful stay at the Boston Harbor Hotel. From the moment we booked, Demetri went above and beyond by helping us secure one of the best harbor view rooms, and it truly made our weekend special. Waking up to the waterfront views was unforgettable. The room was spotless, beautifully maintained, and extremely comfortable. Every staff member we encountered was friendly, professional, and genuinely eager to make our stay memorable. The hotel bar was excellent, with great cocktails and a welcoming atmosphere, and the overall service exceeded our expectations. If you’re planning a trip to Boston and want an exceptional waterfront experience, I highly recommend the Boston Harbor Hotel. A special thank you to Demetri for making sure we had the perfect room—we can’t wait to return.
