when i was linz a couple of years ago i stayed at the marriott linz. the hotel has all of the amenities of a better business class hotel. they offer underground parking at a reasonable price. there is a bar and restaurant on premises. the rooms were modern and clean. located on the europaplatz the hotel is with in walking distance of the sights of central linz. i would recommend this hotel to visitors to central linz.
Another night in another hotel while being on business travel.
Rooms are quite big compared to other hotels in Linz. The bathroom has a bath tub. The fitness area in the hotel is a public fitness club and therefore overcrowded but is feature rich.
