We had a great time at The Millhouse! Aida is a very nice host. She arranged a taxi for pick up and drop of at the airport. Aida gave us very good tips about what to do in de surroundings. The hiking trails in the nature reserve nearby are great (it is practically in your backyard). We just took the map that Aida gave us and followed the signs. The house itself is very cosy. A great place to relax, read a book by the fireplace or sit in the spacious garden.
If you want to go shopping. The Lidl is 20 minutes by foot. The trainstation Valongo is a 30 minutes walk. The train will take you to Porto within half an hour. It is definitely worth your while visiting the beach of Porto (and not only the city center).
It is a lovely place and we would recommend it if you're looking for a place to relax and enjoy nature.
