Currently the Marriott is under renovations which takes away from any atmosphere. We found the service to be very spotty. Lots of conventions here which means very crowds for breakfast. We had breakfast included which was the best anywhere. The hotel is right on a tram stop and only a few blocks from the metro which makes the location very convenient. One of my complaints is that they did not have a dedicated consierge. That makes it difficult to get suggestions on tours or make arrangements.
We stayed end of Sept 2008. We decided to get a corner jr suite and if you can fit it into your budget, the sweeping views across the river are spectacular. I think all the rooms have a river view, but be advised that all may not have a view of the castle. Also, as of late Sept 2008 the work at the hotel appears to be wrapping up. We had no impact except the fitness center is relocated to an adjacent building and has minimal facilities.
