Lisbon
Tiled hills, cheap seafood, and the best sunset spots in Western Europe. Stay 3–5 days, or 5–7 with sintra and the coast.
Arguably the best all-round travel month: warm enough for southern Europe, cool enough to walk all day, and before the summer prices.
Easter is the exception — expect a spike in prices and crowds across Catholic Europe for that week.
World-class food, walkable neighbourhoods, and prices that still feel like a mistake. Stay 4–6 days.
