This was our first experience with Airbnb and we couldn't have been more pleased. The room was comfortable and clean, and the location couldn't have been more perfect. We saw nearly everything on our sightseeing list and we didn't take a bus or the metro once (although in one day we logged nearly 13 miles!). *Bonus tip: you MUST go to Mercado Centrale in/next to the train station. They have the most amazing truffle pasta and gelato. There are other food vendor shops there, too. I could have eaten every meal there. Delicious!*
