Luca's apartment is at a very good place, St Marc Square is about 15 minutes walking distance, and about the same from the train station. We received good suggestion for restaurants, which we tried, and the foods were delicious, and gave us the Venice feeling. The apartment is clean, Luca is communicative and really helpful. During our stay the air condition system was a bit noisy (however the cooling was effective, but you can change the temperature if you wish with the help of the host, this we didn't try), but it might be, that it simply needs just some repair. I bought a pair of earplugs for myself, my girlfriend sleeps deeper than me. Check out was easy, and as we drank a bottle of wine from the fridge (price list is clear, and the fridge is filled with wines, beers, and some soft drinks), I just could leave the price under the key on the table. So the trust from the host is definitely there.
