For the price, especially for the world cup, it was great. It is clean, staff is helpful and friendly. Of course, it's only the basics, nothing luxurious and you share a dorm. Warm shower, clean bed, two big shared bathrooms, and there was no rush. But it's a great way to make friends, especially during major events like the world cup or Olympics. You can bring your kids and family and get a dorm for yourself. Niteroi itself is nice with good beaches. It is quieter and safer (than Rio). It is a bit far from Rio. But you can walk from the hostel mostly along the beach for 20 mins, and then catch a nice ferry to reach the city center (for R$ 5 or so), and then the metro. You can catch the ferry back, but I think the last ferry returns at 9 pm or so. If you stay on in Rio, you would need to catch a cab back. Cabs can be a bit expensive (around R$ 80 from Rio to Niteroi, during the world cup). If you don't know Portuguese (and Spanish), communication can be tedious. Bring your quick language guide.
