I stayed twice in this hostel. If they had more availability, I would have stayed more days.
First time, Carlos checked me in, he insisted to help me carrying luggage up, as he can see I have problem with my legs, even though he was busy. Second time, Edida checked me in, she also offered to carry my luggage up.
Beside nice staff, this is also a beautiful facility, large kitchen, plenty toilets and showers, most impressive is the backyard, this hostel is located in the city center, but the backyard is so nice, open, and quiet.
I can not say enough good about this hostel. I will certainly stay again if available when I visit Porto again.
