The apartment was perfect! It is in front of the metro station Trindade. The airport line got you there directly so it’s very convenient. All the metro lines converged in there. That is in case you need to take the metro because lots of sightseeing are at walking distance. I couldn’t stress more that the location of this apartment is perfect. There is a supermarket less than 100 meters away from it.
The room was sparkling clean and you’ll have everything you need for a good stay. Everything works as intended. As a good extra you even have washing machine which is awesome when you are traveling several days. We totally recommend this place. It will be our first option if we come back to Porto in the future.
