Helena is a true superhost and I now know what Portuguese hospitality means :) She is easy and fast to communicate with, she explains everything very well, her house is very nice and the room was just as described, large, very clean and tidy, and had it's own large private bathroom inside. Everything was working and location is perfect for exploring Porto!!!
She greeted me in person when I arrived and gave me a cup of fresh squeezed orange juice and a cookie :) In the evening she brought a little port and pastel da nata :) These small sweet touches really made my stay!!! :) She also let me store the luggage in her house after check-out for a few more hours.
I highly recommend Helena as a host and her lovely house for staying when visiting Porto. Obrigado Helena! I hope to visit you again! :)
