When visiting Vicenza, I usualy stay in hotel "Palladio", it is not an classy hotel but because of its location it is very convinient.
A single room + breakfeast costs 60-70 euros.
Unique Quality: The hotel is situated in the very heart of the city, just about 100 meters from Piazza dei Signori and Basilica Palladiana.
I suggest you booking in advance.
Directions: in the heart of the old core of the town
