Most people write to me having already chosen. They have seen the Atlantic light in Cascais, or the mist coming off the Serra in Sintra, and they decided before we ever spoke. Then they spend a week here and change their minds.
The two towns sit half an hour apart and photograph the same way. Living in them differs, and the differences do not show up in a listing.
Two climates, twenty-five minutes apart
The Serra catches the Atlantic moisture and holds onto it. That is why the gardens in Sintra are extraordinary, and why the houses there need looking after in a way coastal properties do not. In February you can stand in Sintra several degrees cooler and considerably damper than Cascais, twenty-five minutes down the road.
If you are coming from a dry climate, sit in a Sintra house on a February afternoon before you commit to one. Some people fall for it. Some people last one winter.
What your week looks like
Cascais rewards you for walking. The centre is compact, the market is a real market, the international schools that draw families sit close by, and the train into Lisbon runs along the water. You can arrive without a word of Portuguese and function from day one, which in the first year matters more than most buyers expect.
Sintra assumes a car. The houses spread out, sit further back, and often end at a gate down a lane. That is the appeal. It also changes what a Tuesday evening looks like when you want a loaf of bread.
Cost, and what you get for it
You get more space and more character per euro in Sintra. You get more convenience and an easier resale per euro in Cascais. Estoril and the parishes between them land in the middle on both counts, which is where a lot of buyers end up once they stop comparing the two extremes.
Older Sintra properties need work. Do not let that put you off, because some of the best houses I have seen are there. Get a builder to price the roof before you make an offer rather than after.
What I would tell a friend
Come for a week outside August. Do the school run at eight in the morning in both towns, even if you have no children, because it tells you how a place moves. Buy groceries. Sit in a café on a Wednesday instead of a Saturday.
Then decide. The house will still be there.
