Fabricio has done everything right. He was very welcoming when we arrived, and gave us a few tips for visiting Porto. He was very flexible and communicative - there was absolutely no problem to check out a little later, which was something that very well appreciated as it made things much simpler for us afterwards.
The place itself is well located and has a lot of space, with a living room for us to relax after a day of sightseeing.
I would 100% recommend this place for a stay in Porto. Keep up the good work, Fabricio!
