We stayed at Davids cosy gem apartment which we loved. It's in a perfect location for getting around Rome, everywhere is in walking distance, the Vatican being the closest no more than 5minutes. An added plus is so many amazing restaurants, for our evening meals we didn't go more than 2 minutes from the apartment. We ate at Ragno D'Oro which is just around the corner, great food, atmosphere with a real family feel and amazingly cheap we were shocked at the bill for all the food we ate.
Next door was L'Osteria di Birra, really cool bar brew a few of there own beers, serve cocktails and again great food. Prisco being the farthest at 2 minuets down the road was the best carbanara and cheesecake I've ever had. Davids apartment is spotless and has everything you need for a base to explore Rome. Perfect!
