It is a very nice apartment in a charming building. Even though it is situated on a busy street, it was absolutely quiet during the night. Not a sound from the street or the neighbours!
The apartment itself was very clean and cosy. It looked exactly like on the pictures. The bed was comfortable and the bathroom was spotless. There's a kitchenette in the apartment in case you want to prepare yourself something. We did't use it, since there are lots of places nearby where one can go for a drink or to eat.
Also there are many many little (souvenir) shops on the same street and bigger shops on Corso Umberto which is within a walking distance.
Airport bus stops on Piazza Garibaldi and it took us only 10 minutes to get there on foot from the apartment.
All in all, I would definitely recommend this place - it's well worth your money.
