We had a good experience at Optimum, though it was pretty hard to find as there are no signs anywhere near the street. We had a private room, which was comfortable and very clean. The shared bathrooms were ok, though everything was always very wet. At any rate, we usually didn’t have to wait very long to access them. The building itself is old and very interesting! The hostel is in a convenient location - close to just about everything we wanted to see. Shops and restaurants are a stone’s throw away, so it would be hard to find something better at this price. I’d stay there again.
