Renzo's apartment is perfect!! We only had a few days in Rome, but gladly would've stayed longer. The apartment is really cute, super clean, and in a great neighborhood. It's not walking distance to all the major historic sites, but that works in your favor; you get to experience a great neighborhood and non-touristy restaurants, cafes, etc (plus much better prices than what you will find near all the sites). You can reach all the historic sites very easily with public transit, which is reliable and cheap. Plus Renzo has an extensive guide on how to get to each place, which made it super easy. He was also very accommodating with our check-in and check-out. Highly recommend!!
