Despite its name, CATS hostel does not host any cats. What it IS host to is the title of one of the best party hostels in Porto. Their common areas include a great rooftop, a terrace where they hold BBQ, and a bar with quality snacks and drinks. Not to mention a fully equipped kitchen, so you can show off your skills to your fellow travellers. It is located walking distance to some of the city’s main attractions, so transportation is something to forget about. Be social, have fun, and party.
