Pros: This cosy flat is in the heart of Cascais but away from the noise. You have complete privacy while getting to stay in an authentic Portuguese apartment. We barely used our rental car. The check-in process is seamless from the minute you confirm your reservation (they are very quick to respond). The shower pressure is good, there is a hair dryer with a curly diffuser attachment, and plenty of towels. There is enough space to lay out a yoga mat and the wifi is very good. The dining table is good for working and eating and eating at home with the windows open is pleasant and quiet. The bedroom has blackout blinds for sleeping. The flat comes with a complimentary SIM card with a good data and call plan if you are visiting Portugal.
Cons: The kitchen is small and does not have oil, vinegar. It does have pots and pans but does not come stocked with anything else if you plan to cook proper meals. The photos listed shows a bright apartment but its quite dim inside (In the evening the lighting is nice inside) The rooftop is not setup as shown (but the view is quite nice). There is a newly installed AC (pro) but it has some recurring noises when turned on which just needs to be looked at. Otherwise the bedroom is very nice to sleep in.
FYI - This listing is managed by a local property agent who was very communicative, and went to great lengths to offer us a later check out and answer any questions we had. (We did note a few repairs during our stay and they offered to fix it while we were there though we opted for them to arrange it after we left)
