Gui’s property is lovely and the location is excellent - check in was super easy and smooth, and Gui herself was so welcoming and gave us lots of advice on where to eat, what to see etc.
Also we had to change our trip a few times in 2020 and 2021 (due to Covid) and each time Gui was completely understanding, super flexible and helped accommodate us so we could finally get visiting Cascais in 2022!
The only possible area of improvement is that there is just one air conditioner in the house (on the top floor) and a portable fan in one room, so the bedrooms on the other floors were quite hot at night. This would not cause a problem most of the year in Cascais but it might be worth having air con or fans in some of the other rooms too for summer months!
Other than that, it was a perfect stay, perfect location and I would 100% recommend :)
