Welcome to Dupont Circle and, more specifically, welcome to the Chastleton.  The Chastleton dates from 1920 and boasts a full renovation, down to the plumbing, electric and HVAC systems, in 2007. The building offers what no other Dupont Circle building can with its front desk service, on-site management, fitness center, ballroom, roof deck, courtyard, central heat and air conditioning. The building contains 300 units, yet provides a small and friendly community feel.
