Budapest -

• Mercure Budapest City Center Hotel
• Pullman Budapest
• Nemzeti Hotel Budapest - MGallery Collection

Prague -

• Mama Shelter Praha
• Novotel Praha Wenceslas Square

Vienna -

• Mercure Grand Hotel Biedermeier Wien
• Novotel Wien City
• Hotel Mercure Wien City

We stayed at Novotel Budapest Danube a couple of years ago and would happily recommend it. Great view out of the Danube and of the parliament. Trams make getting around pretty easy.
