This apartment is fabulous. Pure Italian design and right on piazza navona. The windows are sound proofed and the views amazing. I would not hesitate to rent this apt again. We have rented for years in Airbnb and this is the best yet. The lift actually works and the kitchen is amazing. The management company is very responsive. If you are two family's there is plenty of space but the master bed/bath is much grander so you'll have to flip a coin or apportion costs.
Restaurants to eat at. Navona, go to pace dell platino and eat the truffle beef. In trastevere go to horatio glass which is great but expensive. We brought our 5 and 11 year old and they loved it (must be well behaved as this is upscale with no outdoor seating)
