The apartment is very nice and well furnished. The location is fabulous right at the beginning of the main UNESCO Baroque street. Luca also has excellent dining suggestions. We especially liked Al Vicolo Pizza & Vino which is nearby and open on Sundays. Go when it opens 7:30-8:00 (there is no wait then- mostly tourists). The locals arrive later and then you must wait for a table. It had the best pizza we have ever eaten (they even have a five grain crust option). They are big and it is best for two to share. Their salad bowl is great, too. You pick what ingredients you want (you can choose as many as you want for the same price including radicchio, cooked spinach, zucchini and eggplant, mozzarella, Parmesan flakes... It is huge and tasty.
To get to Luca's place: From the airport take the Alibus express bus (€4) from just outside the airport to Stesicoro. It runs every 25 minutes. From the train or bus station take the Metro one stop to the Stesicoro station. The Metro costs €1.
