Lovely apartment and very clean place as stated. Anna is a great host ,very friendly and helpful with any questions we needed, she even arranged our taxi back to the airport. The place is very close to the Vatican and there is a bus 46 just 2 minutes walk from the apartment which takes about 25 minutes (9 stops) to Piazza Venezia the centre of Rome or you can get off earlier if you want to go to Piazza Navona, lovely place with loads of Restaurans and close to Pantheon and Trevi Fountain.
The apartment is about 10 minutes walk to San Pietro train station very convenient if you want to take the train from Fiumicino airport (cost 8 euro p.p) instead of a taxi (48 Euro fix rate), but you will need to change at Trastevere station, you can check it on Trenitalia website. The shops are very close with banks, pharmacies, bakeries, gelaterie restaurants and there is a supermarket 5 minutes walk which is open 24 hours. Perfect place to be, comfortable beds and airconditioning in every room. I defenitely highly recomend it!!
