I only stayed one night with Manuel and his family, but it was a memorable stay and i would indeed recommend you to stay at his place!

The apartment is located in Vila Nova de Gaia, on the south bank of the river, and has sweeping vistas over the city and the ocean. While the area is decidedly residential, a brisk walk down the hill takes you to the centre, or a metro stop.
The rooms are well equipped, very bright and clean. Breakfast was included and in all the room was good value.

We spent our evening there having dinner with Manuel and his family, which was thoroughly enjoyable! Manuel is a very talkative guy, and has all manner of plans and ideas going on, and he is quite industrious. Made for a good chat, and coupled with great food it made it a special night.

Would definitely recommend staying at Manuel's place!
