I have happily backpacked my way through 88 countries in the past 20 years but this place will last long in the memory as an awful hostel run by a bunch of chancers. We soon nicknamed it the Hostel of Doom.
The first and biggest con is that they promise a free pick-up and drop-off shuttle service - vital as the hostel is way out of town on the edge of the sprawling Alexandra township. On arrival, they say they will pick you up from Marlboro Gautrain station. I got there and had to phone them five times before they turned up after THREE HOURS. There were no buses or taxis at the newly-opened station and they kept promising they were on their way when they weren't. Once at the hostel, I discovered that two to three hours had been everyone's average wait.
From then on, there was no free shuttle at all. Either you had to arrange your own transport (and none of the taxi drivers in JoBurg had the first idea where the place was as it was in the middle of nowhere) or you had to pay the hostel rip-off fares for the 'free' shuttle. We called them at one point to be picked up from where we had been dropped off in Sandton, agreed it all, waited and waited, gave up and caught a taxi - to find our 'driver' doing a barbecue at the hostel.
The hostel had power cuts every few minutes that made charging phones or using the internet largely impossible. There was very rarely any hot water and the rooms were bunk beds in freezing cold dorms. The temperatures were sub-zero at night (it was the South African winter) and you had to wear jackets, scarves, hats etc.
The rooms and bathrooms never seemed to be cleaned properly that I could see and the manager Aaron did not appear to have any idea who was staying there at any given time. They had lost people's bookings, moved people's belongings from one room to another without telling them (I came back in the early hours one night and had to hunt for all my gear in the dark from room to room) and were unaware that some people staying there had just walked in and stayed without paying after realising how shambolic it all was.
The chancer owners had hiked their prices fourfold for the World Cup and their main role seemed to be to turn up each morning and encourage as many people as possible to pay for breakfast (the one thing that was decent but costing an extra 40 rand a pop).
I stayed in regular basic hostels on Long Street, Cape Town afterwards and some beautiful ones on the Garden Route. I roughed it in Port Elizabeth and Bloemfontein, as I have all over the world. Long after I left JoBurg, I ran into people still complaining about Gemini. There was a shared spirit of surviving the Blitz among all who had been there.
This place stands out a mile. It was a disgrace and you should steer well clear!
