A Boston developer wants to showcase the city's innovative spirit and fight the onslaught of short-term rentals in his upcoming South End hotel. "This is like an Airbnb killer," Mount Vernon Co. founder and Chairman Bruce Percelay said. "You get your Airbnb pricing, but also a social experience." Boston's hospitality industry notoriously has Airbnb in its crosshairs, and Percelay thinks his upcoming Revolution Hotel will take back some market share. Formerly a hostel, the Revolution, at 40 Berkeley St. in the South End, will feature 164 rooms targeted at younger travelers. The hotel rooms are on the smaller side, but the developer said that is why he is going to be able to make his hotel one of Boston's most affordable. The Boston and Cambridge 2017 average daily rate for hotels was $258, according to Pinnacle Advisory Group. Rooms at the Revolution will average around $150 per night, and Percelay said guests should not expect accommodations akin to the property's hostel past, although some will have shared bathrooms. "It's not like you're slumming it," he said. "It's very cool."
