Location couldn't be better, situated within Cascais old town, in a renovated building, everything new and impeccable. Cozy apartment, comfortable furniture and beds, had all main things needed for a short or longer stay.
It's in walking distance from all Cascais main attractions and restaurants, but situated on a quiet street. Great internet made it convenient for work as well.
I strongly recommend for small families, that is all you need and much more for a pleasant stay in Cascais.
Just keep in mind that since it is within downtown Cascais, you won't be able to park next to the building, but there are plenty of places a couple of blocks from the building - usually paid, but reasonable prices.
