The place was super lovely! Terrace view was amazing, the apartment clean and spacious, the neighbourhood is quiet but pretty much still in the historical centre of Porto.
The only thing which is only 4/5 stars is the check-in. I think if a bigger company such as the one managing this airbnb is involved, they should have a key box on site or a code lock, instead of actual keys having to be picked up in their office. This would make things more convenient.
Thank you for the great stay!
