I travel a lot using Airbnb and loved Carmen’s place more than most. The location near the train station is very convenient for getting there from the airport and to the rest of Italy via rail. All the sights are within walking distance (though you will put in some work) and there are plenty amenities within a couple blocks. The apartment itself is very comfortable, with a great shower but event better, a life changing espresso machine (I am going to buy the same one when I get home). As long as you don’t have a problem with walking, you’ll love this place.
