For people who care about the difference- this place is more a straight hostel rather than a shared apartment, complete with a check in at reception. Check in was smooth and easy, as was all communication.
The space is great, everything is very clean, and it has lots of amenities that really smoothed out our travel experience and made it much less stressful. There's a separate smoking area, which didn't affect the entire place but does leave a trace in the communal sitting area (but not anywhere else), which didn't bother us because we were too busy exploring Porto!
