This is a wonderful spot, right on Piazza San Cosimato and convenient to all that Trastevere has to offer. The place is spotless, with nice touches (such as milk, coffee, toast and butter) provided on arrival. There is a playground directly across the street, which made it perfect for us, as we travel with our two-year old. Another amenity is the film festival which runs all summer in the piazza right outside the front door. We were able to enjoy a film every evening with popcorn and wine between dinner and tucking our little guy in for the evening. If you are traveling with a child, there is no better option than Lamberto's place.
