The flat is easy to find and in a great location from walking into the historic parts of town (Piazza Navona is round the corner) and the bridge to the vatican and castle s'angelo is also round the corner. There are great places to eat, drink and also pick up food around the flat too, most of them are actually non-tourist traps which is handy!
I also loved the niche furniture and hand-made aspects of the flat, it has a very personal feel to it. It's a small size but it has all the things you need like kitchen, shower and sleeping area.
