travelling for work and stayed 3 nights. Not sure how much this hotel cost since someone else booked it for me, so maybe I would change my rating if I knew. Also I spent very little time interacting with staff or using hotel Amenities since the meeting I was attending went from early to late, So do not want to say its too good or too bad, but this was a nice stay overall and the score I gave is based on the following

Cons:
very very small room
Work trip and no iron in the room (would not have noticed this on a personal holiday)
Check out procedure extremely slow
Breakfast quite average
Espresso machine in room (great!) but no milk for the coffee (but maybe this is normal in Italy?)


Pros
Room furnished quite nicely, design style
nice and bright
Extremely clean.
Nice bathroom including tub with Jets (never tried to use it)
Great location- right on the square which was very pretty,
Wifi included in the rate

We selected the hotel "Duchi Vis a Vis" because of the good recommendations at TripAdvisor and we really loved our stay, although it was only for one night. The hotel is located in a very good area, both for sightseeing, shopping and entertainment, the hotels are comfortable, clean and spacious.
The price of course reflected the quality, if it would have been a little bit cheaper, I would have awarded the full five stars.

We stayed in the Vis a Vis during a weekend break in Trieste and were very pleased with the hotel. The rooms are bright and airy, the décor is modern while still in keeping with the traditional architecture of the building itself and we had a lovely view out onto the plaza. The impressive lobby area houses an interesting collection of artwork which added a nice quirky touch, my only complaint would be the lift which was extremely rickety – we took the stairs!
There is no reception in the hotel so you check in at their sister hotel across the road and have use of their communal facilities. One of the most enjoyable of these was breakfast which is served in Harry’s Bar overlooking Piazza Unità D'Italia – a highlight of our weekend, it’s worth staying here for this alone!
The hotel is right in the centre close to everything of interest. Ideal for a weekend break but it would also be perfect for business stays as rooms have a nice work area, free WiFi and is a short stroll to the Congress Centre near the marina. Overall I was very impressed

Excellent central location. Clean and comfy room but the huge shower head over the bath flooded the floor -still I wasn't cleaning it up!! Good breakfasts too
