The location was perfect. The metro was nearby and could bring you everywhere. Since Porto is not a huge city, it was also easy to walk. Most of the time we walked one way and got home with the metro.
The room itself was great. It had a separate kitchen with toaster and watercooker. That was very handy.
It was big enough for 2 people and it was clean.
If you want to stay there you should bring your earplugs though. The room was at a busy street and since there was no AC or ventilator in the room we were dependent on the windows to open and close. Due to traffic (even at night) and partying neighbor tourist we couldn’t sleep, so it is advisable to bring earplugs for a goodnight’s sleep.
