The view from Bernardo's place is absolutely amazing - it's up on the cliffs and has a panoramic view of the coastline. The patio area and hammocks outside are a highlight.
I wouldn't recommend staying here with more than four adults however. The listing says seven beds but there are two doubles and then a very small bunk bed and the seventh bed is quite a thin mattress in the window i.e., more of a window seat than a bed. We were six adults and those not in the double beds weren't very comfortable. I think the place works best for four adults and two children.
I definitely recommend a rental car as the location is quite remote (and stunning - but if you're planning to go into Cascais a lot or travel to places like Sintra or Lisbon then its quite difficult without a car).
The place was very clean and the kitchen is well stocked. However, it is a little more tired than the pictures would suggest.
Rita - who runs the property for Bernardo - was very helpful and responded instantly to all of our queries.
