DON'T BOOK THIS PLACE!
We rented this place for 4 people, 12 days.
We only stayed 1 night.
First of all, the ceiling in one of the bedrooms had big black stripes of mold!
Second of all, the electricity kept turning off, when we tried to cook (!) using the oven.
Third of all, everything was dirty... Many kitchen utensils were dirty, shower curtain had many mold spots, it was so disgusting.
Also the neighborhood is very questionable, we drove by a bar not far from the apartment, with shady people outside.
In the night you can hear everything from outside. It is so noisy - people talking outside, neighbors dog barking all the day and night etc.
We were there in november, and it got so cold in the night, even though the heaters were on.
The only positive thing we can say about this place, is that it is close to the Douro river.
We would never recommend this place!
