We stayed here for five nights to enjoy the beaches of Cascais. For two people the flat is very spacious (it even has a dresser!) and features everything you need. The amazing kitchen is fully decked out, there is an AC unit in both the livingroom and the bedroom and there even is a small balcony to hang dry your beach stuff.
The interieur is done very tastfully and modern.
Location is amazing, the beach is right around the corner as well as shops, restaurants and so on. Noise is no issue at all if you don't go to bed before 11PM (but it's Portugal- you shouldn't go to bed before 11PM anyway).
Communication was great and checking in and out was super easy.
We would definitely come back again.
