The Budapest Marriott is located along the Danube with beautiful views of the castle, Chain Bridge, etc. Great hotel and location! The Prague Marriott is very close to the Old Town Square. Another great hotel and location. And, the Vienna Marriott on Parkring is another great hotel and the best situated for siteseeing. If you click on Advanced Search and enter each of these cities, you will see previous posts and Insiders' photos of these properties. Enjoy!
Stayed at the Budapest and Prague Marriotts. I would rate them above average and convienient to local transportation, shopping and resturants. Lots to do and see within walking distance of each property.
I have been to two of the 3 cities stayed at Marriot locations. The hotel in Prague was very nice, and I felt the customer service there was great and really helped make it a better experience (I find the concierge service, particularly in Europe is very hit and miss). In Vienna I stayed at the Renaissance. The property was wonderful, but I would not stay there again. It isn't too far from the main part of the city, but far enough that I wish I hadn't been wooed by how cool the hotel looked and its name.
