Not sure if you can beat this location in Rome. We could walk to everything in 25 minutes or less (many places 10 minutes or less). It's tucked away in a nice area just west of Piazza Navona. The casual restaurant Cantina e Cucina is 20 steps from the apartment and a fantastic place to eat. We ate there twice out of 4 nights (something we never do in a city the size of Rome). Also a Carrefour grocery just a short walk away to pickup some food/drinks. And gelato places, etc are very close. The hosts were very helpful any time we needed them. The apartment is very spacious and clean.
