Flanked by busy shops, restaurants, and courtyards, the red-brick Charles Hotel, with white-framed windows, injects new vitality in a centuries-old, yet continually changing, neighborhood. From master planning to the design of graphics, signage and even restaurant logos, CambridgeSeven unified the hotel and its companion buildings of Charles Square in a consistent and harmonious expression. After completing the original project in 1985, CambridgeSeven returned in 2009 to update the interiors. The hotel’s 300 guest rooms were designed in a distinctive variety of sizes and types and were furnished in collaboration with Hirsch/Bedner Associates. The presidential suite atop the hotel commands magnificent views of Cambridge, Boston, and the Charles River.
