Giovanni's apt is superbly located a 10 mins stroll to the Vatican. Its towards the end of bus route 64 which crosses the city from the main train station. The apt itself is very nice, large and stylish with all the amenities you require. Giovanni provided a very considerate welcome pack, bread, cake, juices etc. Also his colleague Fredrico gave us some excellent advise on what to visit and get around the city. Highly recommended.
