"Cromwell Place Café is the most serene spot on this list. The cafe is inside an exhibition space in South Kensington, and there’s a strong chance that the sound of a classical jazz concert happening next door will drift into the room. Tap away underneath high, stuccoed ceilings while staring at a marble fireplace. Nab the big communal table if you’re with a group, or stick to the curved corner sofas if you plan on making (quiet) calls." - jake missing, rianne shlebak, daisy meager, sinead cranna
