A new hotel is opening on the border of Park Slope and Carroll Gardens. Residents and local business owners have mixed reactions to the new hotel, which is set to open June 1. Residents say they need a hotel because there are very few around for friends and family to stay. But others worry the hotel is a sign of gentrification and that they may soon be pushed out. Hotel representatives say they hope the hotel will be an asset to the community. The Brooklyn Chamber of Commerce says the new hotel and the expansion of the Marriott show there is a demand for more hotels in the borough.
