The 252-room Hotel Indigo joined the ranks of Savannah’s boutique hotels with a ribbon-cutting ceremony Wednesday to mark the opening of the hotel, at 201 West Bay St., on the site of what once was the Guckenheimer tobacco warehouse and grocery, a nationally registered landmark built in 1850. The property was more recently known as the Inn at Ellis Square until it was sold to Atlanta-based Noble Investment Group in October 2014 and underwent a complete face-lift. “We are excited to welcome guests to the Hotel Indigo Savannah Historic District in the heart of City Market at Ellis Square,” said Kellie Lindner, hotel manager.
