We stayed at Luca's place for three nights and it was one of the best option that we could choose;
Location is fantastic! (Several routes checked: 10 minutes to Rialto and San Marco, millions of souvenir shops, Coop, amazing homemade pasta bistro in 5 minutes);
Even better than location was Luca himself: he gave us the most detailed description of the route that you can imagine, afford to come earlier as proposed time and gave brief but super informative instructions about "must see" bars/places/routes;
Unfortunately we had too little time to taste everything but surely try to come and surely stay at this rooftop nest!
