The appartment was honestly perfect. Spacious, calm, plenty of room, wholy equipped kitchen, cozy...
Beach is 15/20m on foot. It's a beautiful wild beach with a very nice wooden plank walk on the sand : perfect for a run.
It's easy to go into the center of Porto with an Uber (20 minutes and in this time of covid crisis, 8 euros for two, 15 for 3). (You can go with public transportation but beit takes minimum 40 minutes / 1hour).
We work remote so we stayed at the appartment a lot. WiFi was good. Chairs and table were confortable. The supermarket is close and has everything (it's super big and cheap).
Also, if you love dogs, it's the place to be ! (I think it's part of the contract around there that you have to have a dog if you want to move in haha)
