Harborside Inn Of Boston

Harborside Inn Of Boston

10/10 Excellent
"Everything was very good about the establishment, the staff was awesome from getting us into a room as quickly as possible to giving us very good directions and lending us umbrellas. The Voia had very tasty food and strong coffee. ;). It’s located in the financial district so one will pay a bit more, however well worth it. It’s in walking distance to many sites, shopping and food as well as the trolleys, bus and train services. Be prepared to walk if you don’t rent a car, we have no regrets on not renting a car, we would definitely stay there again in the future."
