The apartment is much bigger and more spacious then you'd expect from the pictures. It's in great location, within walking distance to main tourist attractions and metro station, plenty of restaurants and shops nearby.
There was very little hand soap at the bottom of the bottle, which was very inconvenient as we were using two bathrooms. Some shower gel, but no shampoo.
The person who greeted us couldn't give us any advice on shops or restaurants in the area; we arrived Sunday evening and were told everything was closed already, which was far from truth.
Overall, we had a good stay, the apartment met our expectations and we would consider staying there again if we're back in Porto.
