We had a wonderful 6 night stay at Luis' place. The apartment is as perfect as the pictures make it out to be - beautifully decorated, very clean, and very well appointed in every way. The kitchen has everything you need for home-cooked meals to just heating up leftovers. The view is beautiful and the location is perfect. There are several places to eat and buy groceries within a short walk and you can get to the beach and ocean walkway in a couple of minutes. There you will find restaurants / cafes / bars and it is a beautiful walk down to Cascais along the water.
We worked from the apartment a few days, with no issues with the internet and were easily able to park our car overnight on the street outside the apartment.
Easy communications with Luis, he was very responsive and a great resource for area information.
We would highly recommend staying, and we would happily stay again!
