Marlene was a caring and helpful host, always ready to share some tips and interesting city locations. When we arrived we found Porto wine with 2 glasses and postcard with nice message in our room which was truly sweet and kind.  The house is located in convenient area, between seaside and city centre - it’s easy to get to all interesting spots from there (and restaurants within easy reach). Interior is full of interesting, creative elements - artictic asthetic makes it really unique. However, there are 2 things which you should know if you want to choose this place:
1. The bedroom and shower are actually in the same room, where the bed is - they are separated only by a partition (single wall) behind the bed. For us it was a bit surprising but not a problem at all (the shower is big and comfortable) but if you need some toilet/bathroom privacy, it’s always good to know.
2. The area is quite noisy - if you don’t have a problem with clear sounds of riding cars or trams behind the window, than it’s ok for you. We had to sleep with windows and shutters closed to reduce it all the time.
That's our experiences and suggestions. The city itself is truly great to visit so if you’re still thinking if it’s worth it - just go to Porto. :)
