You will find cleanliness, hospitality and a comforting location to the city.
I would suggest learning about the metro before you come. It cost about 1.50 euros for a ticket to go just about anywhere you want to go from Tomasso’s place (Trevi fountain, the coliseum, and the Vatican for example). The metro is about a 3-4 minute walk away. They have staff there that know English and could provide you with a map of all the routes. You can also buy trains that go outside of Rome for about 14 euros a piece to just about anywhere.
I would also suggest buying the proper charging port for your phones before you come. This was my first trip abroad with my wife and we didn’t even think about the fact that you need a different one. The port for Italy has two prongs on the end that are cylindrical, which is unlike the flat, rectangular prongs on the American charging ports. You can also find these ports around the city for about 7 euros. You will find people selling them on the streets around Rome.
Tomosso is a great host. He’s very friendly and responds to request almost instantly. Don’t be afraid to text him and tell him the problems you are experiencing. Also, ask for suggestions from him. He gave us a google map of wonderful restaurants around the area that you could check out. All we had to do was open the map on our phones, and then follow the directions to the locations we wanted to go.
I hope this helps!
Ciao!
