This is a very lovely and cozy studio, well equipped apart for washing clothes and if you plan to stay a longer time it will be very inconvenient for washing clothes in this area. It is quite remote to Vila de Gaia (10 min walking). Also, it is a bit humid but this is due to the area where the flat is.
Then, if you are a digital nomad or a professional, wifi speed is very good but the neighbourhood can get easily noisy during the day, there are narrow streets and people talk around, dog barks and also the flat walls are quite thin so you can easily hear around.
However, it is a very good spot because you are far from city noise and close to it at the same time. I had a bicylce so I would enjoy going cycling in the morning the area is very nice and i recommend going to the Praia das Pedras Amarelas, very nice beach and cycling tour and also closer to Sao Pedro da Afurada, a very lively fish village with great fish restaurants. 10 min on top of the flat you have Graham's Lodge with the Vinium restaurant: amazing view and food ! I recommend it to you.
So overall great stay for short stay according to me but it may vary from one season to another.
The owner, Sergio was very helpful! Thank you Sergio.
