We stayed for 1 week and really liked it.
Firstly, Luiz is very carrying guest. He meet us, despite we arrived at 1 am. He provided valuable local tips.
Secondly, the appartments has all the facilities / ammenities you need. So you feel like at home. The flat itself is very clean as well and it has own parking space (in case you will arrive with the car).
Thirdly, the appartments’ house has indoor pool which is heated, so our children and we used it a lot as the weather was not the best one during our stay.
it is very safe place as well.
The appartments are in Gaia (another side of the river than Porto), but the metro station is 5 min walk from Luiz place. It is possible to reach the old town of Porto in 10 min by metro.
