Kimpton Charlotte Square 
Time Out
Star Service
Time Out "Lurking away behind the classical New Town façade (the building is the work of Robert Adam) is a small pool, a gym and 198 bedrooms done up in a style not uncommon in the city: the 19th century meets the 21st"
Star Service "Active guests will appreciate the TechnoGym-equipped fitness center and spa (although the 12-m pool is too small for lap swimming)"
