The apartment is fine, comfortable enough even for 4 people, well-equipped and really clean. But the location is not great. If you only want to see the Vatican City, it's a nice place to stay, but otherwise it's a 40-minute walk everywhere else. The bus is no solution, since it goes super rarely. Once we waited 45 minutes for it to come. On the plus side: there is a gluten-free Sicilian bakery around the corner (super delicious pastries).
