We had a very good time in this appartment. It is very centrally located in the city: everything in the old center is on walking distance. The appartment itself is very comfortable and spacious with 2 good bedrooms and a modern bathroom. There's hardly any noise from outside during the night, even with the window open. It didn't get too warm neither, without having to use the airco.
Olivia and Rui are very attentive and provided all the information we needed about wifi, parking, laundry, etc. The complementary fruit, coffee and tea were much appreciated.
We can recommend this appartment to any one wanting to visit Porto.
