We lucked into this - Le Volte happened to be next door to our AirBnB and was highly recommended. The food was excellent, the service, from Pietro, the owner, was personal and just the right balance of insightful and responsive. We loved the decor.
Le Volte is in a great location, just around the corner or so from the Pantheon. It's tucked away a bit so not in the obvious touristy areas. It's quiet, beautiful, stately, yet still appropriate for families.
The food is classic Roman food and they have quite a few signature dishes. When you imagine / dream of an Italian meal, this is it. We ate here three times in three days, it is that good.
