About No 284 Back Bay by Sonder

This manor at 284 Commonwealth Avenue, at the corner of Gloucester Street, is a short walk from the shops, eateries, and sights at the Prudential Center, from the Boston Public Library, and from Copley Square, the outdoor plaza at the Back Bay’s heart. You’re a block from the galleries along Newbury Street, and there are more cafes and restaurants nearby than you could sample in a stay many months long. This is all to say: No 284 Back Bay by Sonder has an excellent location.

Like other properties that Sonder runs, including Sonder The O’Connor in Canada’s capital city of Ottawa, their Back Bay lodging is a limited-service accommodation, staffed only part-time but with a customer support rep available by text. You receive an access code to the building and to your room before your check-in, and guests are encouraged to use the Sonder app for information and anything else you might need.
