High end: Kempinski and Le Meridien. Low end: Sofitel (ex-Hyatt) which has cheap large corner suites facing the Danube (complete with dining room which is unusual in a low-end suite). Some great junior suites too (and lots of them, something like 50 suites). High end suite suffered from bad furniture and layout as a Hyatt, haven't seen it since Sofitel took it over (and presumably refurbished it); so the high end suite might be the best in town now.
