Probably the best equipped airbnb I have ever stayed at which made my long stay a breeze. For those that like to cook the kitchen had everything we needed and more. We found the flat cozy, but also spacious, modern and nicely finished. The property looks just like the pictures did at the time when we booked. There was a nice pool, although probably best only in the summer as it was quite cold for us in October, even in 25C weather. The management company was very professional and quick to respond when we needed them.
As far as the location is concerned, it was fantastic to be able to be in Guincho or downtown Cascais within a 10 min drive. It was also only a 15 min walk to Casa da Guia with restaurants and bars on the ocean cliffs. For those with children there's a decent play area within a 3-min walk and another a 10-min walk away. There are a few small grocery shops, bakeries, and butcher as well as a handful of restaurants within walking distance. There was a great take out restaurant called Despensa about a 7-min walk away. If using Bolt or Uber as opposed to using your location, make sure to mark the GPS on the road where the front entrance is as the property is in-between two roads and we had cars waiting for us on the road behind the property several times.
The only downsides to the property were noise related. One flat had an electric garage directly below our bedroom which we could hear when they came home, and we could also hear the above neighbors walking, watching TV, talking.
