In very few sentences: great communication, very easy self check-in, spotless clean apartment. Definitely recommended!
Re. neighbourhood: It's about 5 minutes walking from the Metro, which makes it easy to get to the Porto's centre. Worth a reminder: Metro stops at 2am and it's 24h on weekends.
On the way to Metro, there's a Department Store, including a supermarket.
No free parking, but there's paid parking a block away (the store's parking). In front of the house there's free street parking overnight only (charging starts at 9am just for limited period).
