The place is very well located, the owners are super friendly and you can count on their almost immediately responses and help. Great list of local tipps included. The apartment is clean and provides exactly what is told.
One thing to mention is, that you should be prepared of getting some night life sound - so it is not the quietest, but surely greatly located and nice place to stay in beautiful Porto!!
Warmest regards to Rui and Patricia - you are very nice hosts!
