Service was bad, due to the following reason: we received a smokers room while we didn't ask for this and if you don't smoke yourself it is very dirty to sleep in this smole, the next day we could receive a different room. We also had to give our CC number or pay a hundred Euro security for minibar ordestructions in the room during our stay. We weren't informed with this before we booked and I never had to do this in any hotel before. When I asked the receptionist about this, she reacted stiff and unfriendly. Eventually, we paid 50 Euro security. Both incidents could have been solved by the receptionist better and in a more friendly way, just by talking about this with the customer beforehand.
For the rest, the price / quality standard was very good, and as said before, the staff could be more friendly.
