The brief
A mountain-backed capital with Roman ruins under the streets.
A lighter guide for now, with no curated event calendar yet, so the live parts (fares, stays, weather, timing) come from the agent when you start planning Sofia.

Sofia is quietest in Jan, Feb, Mar, Nov. Off-peak demand usually means softer fares and cheaper rooms. Taller bars mean bigger crowds (seasonality estimate; the agent checks live conditions).
Three things the search box won’t tell you
Fly mid-week: Tuesday and Wednesday departures from London usually price below Friday and Sunday flights on the same route.
Aim for the shoulder months either side of Sofia's peak season: rates drop and queues shrink while conditions stay close.
Let the agent search ±3 days around your dates; a one-day shift often crosses a price cliff.
