The cottage was really cute! It's off the street in a garden, surrounded by lots of lemon, orange and pear trees (lemons were in season when we went so Mafalda very kindly said we could make ourselves lemonade - we did and it was delicious).
Mafalda met us outside the entrance when we arrived in Vila do Conde and was a great host. She was available if we needed her but left us alone when we didn't. The cottage is really close to the metro station for easy access to Porto and to the centre of Vila do Conde and a 25 min walk to the beach.
There are only two slightly (and only slightly) negative things I would note about this AirBnB:
1) some of the doorways are quite low - we are quite tall (I am 1.78m tall) so we had to be careful not to hit our heads on the doorframe. So if you're tall, just worth being aware.
2) there isn't a door to the bathroom, it's closed off with a shower curtain, which we could deal with by going outside or putting the shower on.
Otherwise, we had a wonderful, relaxing stay and are very grateful to Mafalda!
