In August of 2006, I represented an investor working with the Noble Investment Group with their acquisition of the Sheraton Colony Square in Atlanta. The plan was to renovate the hotel and convert it to the W Hotel Midtown Atlanta.
Noble has a link to a virtual tour of the hotel on the home page of the Noble website. (The link is on the top right corner of the picture). Noble also has a case study on Major Renovation of the Sheraton Colony Square to W Hotel Midtown - Atlanta, GA.
