Beware: The host's understanding of reservation of the ENTIRE PLACE means his sharing the place with the guests!
Just do yourself a huge favour and find yourself somewhere else to stay in Porto.
This is exactly what we did the next day. We left this "unforgettable" place and checked into a magnificent Airbnb studio flat, which was spotlessly clean and situated in the heart of Porto: A totally safe and quiet little gem, with a heavenly bed!
Female guests ought to keep away from this place by all means.
