Overall, mixed experience. The building, the rooms and views make this amazing and save the bad experience with service.
My family had some questions about the restaurant or the city, Front Desk barely picked up and made us wait hours just tk finally clarify if there is a table available for at the Konrad's restaurant. Secondly the room was not made one day, and a toilet brush was left in the toilet. Not things you expect from the Marriott as long time members. And lastly the others in our party had the corner sweet, gorgeous view but the living area had a weird furniture with the TV basically on ground level and it was pushed about 1 meter from the wall with many cables exposed, looked horrible and cannot imagine this was the normal design, looked like a botched repair.
All in all, great area and we'll jot this down as an "off day" because all the other things were great, i.e. comfort, room size, views, room service.
