Absolutely loved this place!!! Our Airbnb was a two minute walk from here so we frequented it often, multiple times a day.
San Calisto is a traditional Italian "bar" ... meaning it serves coffee drinks, pastries, beer, hard alcohol, sodas and even gelato. It's pretty much open 24/7, so if you need an early morning expresso drink (early meaning like 6:00am when most places are closed in Rome), San Calisto is the place to visit.
San Calisto has a very locals vibe - I didn't see many tourists when I was there, which is a good thing. It's small, with about 30 seats outside. Outside seating is usually full (except for those early morning coffee visits) ... but that goes to show you the popularity of this place.
Prices are the lowest I've seen in Rome! 0.80 euro for an expresso, 1 euro for a cappuccino, big Peroni beer (330ml) for 1.50 euros ... these prices cannot be beat.
Although they are very busy, service was always spot on and friendly. They were patient with our orders and the payment "workflow" (pay first at the cashier, then bring your receipt to the bartender). Loved the vibe here ... I highly recommend visiting Bar San Calisto!
