We enjoy staying in Mario apartment. The apartment is a little hostel - 5 double rooms and two bathrooms. It is clean and it has a good location. Mario is very friendly, very helpful, everything was explained very well with all the details of the apartment, also has a very funny and helpful map of Porto, with a great design. We got vouchers for breakfast and enjoy it in a Café in St Caterina street ,near the apartment. Thanks Mario
