Massimo's place was super close to the Vatican and only 3 small blocks away from the Metro. It is a clean and private place to stay, felt kind of like a good Hotel. They give you tickets for cofee and croissants from a coffee 1 block away, it is really good and the best way to start your day. There is also a laundry place 2 blocks away, for 8 euros or 4 if it is a small load, they wash, dry and fold your clothes. There is also a very cheap fruits and veggies place (you will find that fruit is really expensive in Europe) 1 block away and a Kebab and pizza place right next to it (I tried the kebab, it was tasty). Obviously I recommend staying at Massimo's :)
