Santa Kafeina is a very small corner cafe on Calle de Viriato, a residential Trafalgar street north of Madrid's tourist core and close to Iglesia metro. The room is sunny, plant-filled, and tight enough that the counter, window seats, and coloured cups frame most of the visit. Go for a short espresso or manual-filter pause with a cookie or sandwich, not a long work session.
Coffee style
The coffee offer is compact: double-shot espresso, flat whites, and filter brewed through methods such as Chemex, Aeropress, or cold drip when the bar is running them. The menu tends to feel edited rather than sparse, with rotating coffees and enough barista guidance to make the choice clear without turning the counter into a class.
Food
The bakes make the stop more than a caffeine errand. Cookies, banana bread, pumpkin-and-chocolate slices, croissants, grilled ham and cheese, and avocado toast give the small room a breakfast-and-snack rhythm, though this is still a coffee bar before it is a full brunch address.
The room
Space is the honest limit. Santa Kafeina works best when you can take a stool, stand near the counter, or carry the cup back into Chamberi; if the few seats are gone, the visit becomes takeaway by design. The weekday hours also make it easier to fold into a local morning than to plan as a weekend detour.

Why Filter Notes has shortlisted Santa Kafeina
Santa Kafeina gives Trafalgar a tiny counter for double-shot espresso, manual filter, and house bakes rather than a full brunch menu. The plants, window seats, cookies, and short food list give the cafe its shape, while the limited seats and weekday rhythm keep it best for a focused pause.
