The apartment is nice, clean and safe and well located. It looks exactly the same as on the photos.
The apartment is beautiful and well-equipped. There are so many things that you can even live there (pans, glasses, iron, ironing board, washing machine, etc.).
It is close to the city center (5 mins walking distance) but in a quiet street. You can see the Ponte Infante Dom Henrique and Villa Nova de Gaia from the window. The bridge is also in a walking distance. It is easy to reach public transport to several directions and there are lots of restaurants in the nearby.
There is a park next to the building. The building itself also looks good. I think it has been renewed because it looks modern in the inside, although it has the pretty azulejos on the outside.
Communication with the host was easy and picking up the keys was also simple. The Castle Rock was not far at all. We did not meet with Jean in person but he was nice and helpful through the messages.
We were absolutely pleased with everything and would be happy to go back again to this apartment.
p.s. it was really cute that we received a bottle of Porto wine as a welcome gift :)
