 "Founded in 1922 in a Lyautey colonial building, and recently refurbished with a great mix of colonial decor." 
 "Set in one of Casa’s architectural gems, the decor at this 1922 hotel is all a bit over the top."

Avoid the 1st floor, as it gets the brunt of noise from the popular and very rowdy piano bar and nightclub.
