I can't recommend Francesco's place enough. The location is perfect for practically anywhere in Rome. The city itself is a very walkable place, and Francesco's apartment is two seconds away from Piazza Navona. ... And if you don't feel like walking its very easy to just jump on a bus.
Francesco was a delight. He always responds to messages very quickly and was extremely helpful!
The place was superbly clean, very comfortable and very warm. There were fresh towels, a hair dryer, pots and pans, and all the extra little things you can think of.
I would definitely stay again!
