Good location, extremely helpful staff (really helped us with everything when we first arrived to Bolivia, from how to navigate the financial crisis and exchange currency at black market, recomending places to eat and visit, to transporation tips and navigation + have spoken a perfect English, which is not a standard in La Paz), cool and pleasant shared area and kitchen.
If you look for a friendly and cheap hostel in a safe and hip neighbourhood, this is dedinitely good choice.
