I had a great stay at Claudia’s, her place is very homely, stylish and the view and light from the balcony is lovely. Foz is a really nice area by the sea , close to her home there is good services..a really good supermarket if you want to cook in and good cafes , restaurants by the sea. I liked that it was an hour to walk into the city..I like been in nature and enjoy walking..the walk in by the sea and then the river is gorgeous. You can get an uber that takes about 10 mins ,7euro....easy.
Claudia is very helpful, thoughtful and always there is if you need anything. And I luved Porto ! Way more than Lisbon for me, the old buildings are amazing, I could walk around and look at them all day :)
