The apartment is very cozy and you have everything you need. The bedrooms are large and comfy. There's also common space where you can eat, drink, talk or whatever you like - it's a great place for a group of friends.
The locations is also very nice. In the neighbourhood you can find pretty much everything - restaurants, bars, pharmacy , supermarkets and even McDonald's just a few steps away.
Except that, if you are energized almost all tourist attractions are on a walking distance from the apartment. Vatican city and St. Peter square are only 15 minutes away. Then you can continue walking to Castle Sant Angelo, through the nice little streets to piazza Navona , Pantheon and many other spectacular places in the historic centre of Rome. Trastevere is also not far away.
Well, to be honest, it's a lot of walking but it's worth it. There is a bus stop just next to the building so you don't really have to do it.
But the best thing was the hospitality of our hosts. They were very friendly and nice and gave us some really helpful tips for our stay in Rome. They also booked us a car for airport transfer and even that there was a misunderstanding they compensated us.
I strongly recommend the apartment!
