Great place to stay at Porto! The location is perfect, it's close to almost every must-see in Porto and it's only about 5 minutes walk from metro station (it's even faster if you walk directly through the mall).
The self-check system is really convenient and the room is very clean and cozy. It just makes you never want to leave the house. We really enjoy the welcome wine (big thank you to Joao!).
However, bedroom is close to the street so it could be noisy at night. And there will be a flood after shower.
Other than that, everything is perfect! Highly recommend!
