Roberto's apartment was very compact and ideal as a base for exploring the city. Roberto greeted us on our arrival and gave us a very handy map which he marked with good places to visit and local restaurants. He also left us some snacks which was a thoughtful touch. It's approx 5 minute walk to the nearest metro which takes you straight to Vatican City. We walked to the Colosseum in about 20 minutes. All in all a lovely stay. Thanks Roberto!
