This is an apartment I would heartily recommend to anyone. The location is perfect. There are walks by the sea - you can almost touch it from the balcony of Alda's place; buses are regular and close by to take you to Cascais and there are restaurants close by if you don't feel like traveling. We did hire a car and toured a bit - and loved returning to the apartment. It's modern, spotless and well equipped. The pictures on Airbnb are accurate and do it justice. A Smart TV and good Wifi was very welcome. Parking was in an underground car park - which kept the car nicely cooled. If you do choose Alda's don't miss the bakery she will tell you about ...
If you go to Cascais for a break this is a great place to stay. While you are there go visit Sintra and Estoril. Thanks for everything Alda!
