The location of this apartment could not be more convenient. We walked everywhere, but when we went to the Vatican Museum and the Borghese Museum we took a bus that was fairly close to the apartment. The flat is also right by the Ponte Sisto bridge which takes you into Trastevere, a lively, less touristy section of Rome. We walked its streets two nights and had dinner there one night. There is also a small shop right around the corner from the apartment with snacks, drinks and essentials. We stopped in a few times during our stay. We used the washing machine and it worked great. We were not able to enjoy the terrace as we were too busy seeing the city, but it is nice and roomy. There were plenty of towels and while we did not cook during our stay, it looked like the kitchen was well stocked.
If you are looking for luxury, this may not be the place for you, but if you are planning to spend most of your time sightseeing, this is a good apartment. We loved our first visit to Rome and the Ponte Sisto house was a clean, convenient place to explore from.
