I have been in many Marriott hotels, but this one was disappointingly under many aspects.
First of all, at the check-in they pretend a deposit of 75 € that is mentioned nowhere between the house rules or the booking information, I have double checked what they indicate here in Expedia an also in the other booking platforms, and this detail is always omitted. Usually the hotels informs prior the arrival if a deposit is requested, its amount and the accepted methods of payment: is a clear lack of transparency from hotel management.
Moreover, they said that it was unblocked at the check-out but bank has not confirmed yet, and I'm still waiting to have it back.
Second: the room was booked for three people: 2 adults and a 4 years old kid, but evidently they didn't take care of this information and the assigned room was without enough sets of towels for all of us.
The cleanliness was also another negative point.. since the arrival walking barefoot I felt that the moquette was full of dust and crumbs.
They advertise themselves as luxury and near Ars Electronica Center, but they are honestly far from both things.
But the the straw that breaks the camel's back has been the incorrect application of the city tax: they charged me 2,40 € per night for all of us, ignoring that guests aged 14 and under are exempt Linz city tax . Guests here are just cows to milk.
