This is the first youth hostel we have stayed... This is a very large youth hostel, and the most important is: It's very clean. We have a double-room, the room is very small, but it's enough for two people. The shower room is very clean... and every one has his/her own key for access to the toilet and shower room, so it's pretty safe.
The breakfast is not included in the price of the room, but as we observed, there's not much food to be chosen in the buffet, just bread and jam.
We have tried once in its restaurant for dinner... the food is expensive and really taste bad. If you want to save money, you can buy food from supermarket in the train station, and cook by yourself in the kitchen of the hostel. Many utensils are provided in the kitchen, and some former residents left their own food for sharing. So, we had cooked spaghetti... and even bowls and spoons, forks are provided!
Don't buy food from the reception, as it is more expensive than buying from outside.
If you go to this hostel from the airport, you can get on 250S (airport bus), then route 100. The driver is quite helpful - ask him to call you when you arrive.
