The best thing about this place is its host, Helena - she is the most attentive and kind woman you'll meet. She'll be available for your requests 24/7 and will leave you little treats in the room. Also, she has some great tips on what to see and knows the directions. You have your own entry and your own keys, so you don't need to walk through someone's apartment in order to get to your room or bathroom, that came in really handy. There is a lot of extra blankets if you get easily cold (like me). The mattress is very good! The place has all you need for a short stay in Porto and is a 1 minute walk from the metro station and not too far from the center.
