Rita and her boyfriend were super nice and friendly, really open and easygoing people. She was accessible and communicative during my stay and checking on me if I need anything, very lovely manner.
Their place is well-located, and there are many bus stations with less than 5min walk. Near to a vibrant and alternative place with many shops and cafes. I felt really comfortable and welcomed at their place. She even made a list of worth-of-visit places, restaurants and cafes.
I will definitely choose her place for my possible next visit to porto. Thank you guys :)
