Myself and a friend stayed at one of the apartments in a PATH apartment block for 2 nights. It was a nice stay, very clean and modern apartment. It feels like more of a serviced apartment than a traditional Airbnb apartment.
Its about a 15-20 mins walk down the hill to the centre of Porto so location is good. Communication was good, we spoke to about 3 people during the inquiry, booking, check in process.
Overall a nice stay at the PATH apartment.
