Wonderful place, great location and fantastic host! Jose was incredibly communicative ahead of and during my stay. He was also super helpful in providing suggestions for where to go (as it was my first time in Porto).
The bed was super comfortable and the apt was super clean and updated. Plus the location was very easy walking distance to all of the major sites.
(*Very* minor heads up for people with longer stays - the closet space is limited, so if you have a lot to hang up, just be aware. There is an ironing board (with steam setting), and as my stay was only a few days, I had no issues.)
Overall, would definitely come back and stay again!
