Enjoy one of the best views of Piazza Navona from the rooftop bar at Lifestyle Suites Rome. The bar offers a great selection of cocktails and wines, and during the aperitif, you can enjoy snacks like chips and olives with your cocktail (recommend the Aperol Spritz). Prices are way higher compared to other places in the city (around 15-24€), but you won't get a view as beautiful as this one in another places. For an even better experience, visit at sunset! When I visited in July, the bar wasn't crowded at all, but if you want to secure the best table make sure to book in advance.

The rooftop bar is part of the Lifestyle Suites Rome Hotel, just go inside and take the elevator to the rooftop terrace.
