We had a wonderful stay at the mill and found that the villa was even better than it appears on the airbnb listing.
It is clean, has a well equipped kitchen and really spacious which was important as a group of six. We really appreciated the pool area as it came with 6 sunbeds, pool floats and the pool was heated so a really nice temperature for a swim even on the few times it was a bit overcast weather-wise.
As the villa is quite out of the way, we ate in the villa most out of the time with a few trips out to Aveiro and Porto via taxi. The kitchen is really well equipped so we were able to cook easily and appreciated the dishwasher. I would recommend getting a car so that you can drive to local shops and areas (Aldi and Pingo Doce 10 mins away) but it's also worth noting that we used the FreeNow taxi app really easily to get out for meals out in the evening when we didn't want to drive.
Marie was really easy to communicate with before and during the stay and we couldn't have been happier with our decision to book this airbnb.
