Perfect little local - it's only downside was being shut on Sunday when we wanted to go there for our final lunch. Really well priced, very 'local' feel, good coffee and really tasty sandwiches. Great cicchetti too, which I only got a small sample of as we always went for brunch and they only really came out at lunch. If I'm ever staying in this area of Rome again, I'll be sure to continue visiting Er caffettiere every morning still.
