I stayed at Dunav for a business trip. The room was very nice and clean. The staff was helpfull.
The hotel is quite near the center and you can walk to nearby You can order breakfast and dinner, but if you want you can cook since there is a kitchen with utensils and a fridge in the room.
There is an excellent Internet connection and TV with various channels for all intrests (FInance, Cartoons, Documentary)
I recommend it.
