We stayed in Nova Hotel around December/ January. The location of the hotel is perfect, it's really close to the city center and not far from the train station. Unfortunatly in terms of confort they could do better... The room was big, which i really apreciated but it was really cold and smelly! We had to let the heating system on for the whole afternoon!
If you are looking for something simple, this hotel might be what you are looking for, but don't expect much..
