It was good to stay there, but don't follow the tips to arrive there, in fact it's very close to the palace of culture. no need to take a bus, it's faster by feet. Just when you come from the airport, you will arrive in front of the palace of culture, turn and you will see a mall with K MARK go there, and you, cross the building and you will be in the street of the guest house. Then go to the hostal which is in a perpendicular street ( the second one) turn to the right and you will arrive at the hostal. Anyway if you arrive during week end , there is no bus goes there. and it's just 10 minutes walking away from the palace of culture.
