Pietro's place is very stylish, and is very modern from the inside (it seems to be recently renovated, so it is very modern while in a historical building). His place is also very well decorated and stylish. The furniture is very comfy - the mattress is very firm and has good back support. The place is well-lit and bright. The shower has very good water pressure. It's close to the train station & bus stop (there's a shuttle to the airport) so it's possible to walk to both places, although you'd have to carry your suitcase across 2-3 bridges (but that seems to be normal in Venice).
