Jacopo's apparment has a very good location and is in the walking distance to Saint Peter square (15min) and to Vatican Museum (25min). Bus station is next to the house and the bus goes to Venezia square (starting point fo Capitol, Vittorio Emmanuel Monument, Forum Romanum and Colosseum). We spent in Rome 4 days, 2 days we were travelling with the bus and 2 days we managed in the walking distance of the flat.
Jacopo's apparment is extremely nice and comfortable, 2 separate bedrooms and 2 separate bathrooms, nice terrase where you can sit. We were also provided with stroller, baby cot and baby chair for our son which helped us a lot.
Jacopo is a perfect host, everything was as agreed, he ordered us a taxi from/to the airport for fixed, pre-agreed price, we got maps and necessary instructions for our stay and moreover we got private tour aroung the neighbourhood.
I would definitely recommend Jacopo's appartment for your stay in Rome, it made our holidays unforgettable!
