Don't recommend this hostel. Its only advantage is that it is very close to the train station. As to rooms, beds, furniture, etc - my dorm in the university was better.
Don't believe the stories that all the center of Warsaw was destroyed by Nazis in 1944. The building where this hostel is located is more than 100 years old. Because of that, there are problems with hot water, and the heating does not work in the end of October. It's quite cold inside, especially in the night and early morning. Just shaving yourself is not so easy, taking a shower is almost impossible. Also, the hostel is on 5th floor and there is no elevator.
The hostel looks a little bit like Soviet Union, but it is in the city center and the price is very low.
The stairs to the 2nd and 3rd floor are almost vertical, like on a ship's ladder. All corridors and doors are too narrow. Not very good if you have a big bag with you. The guy at the reception did not know where is the closest place to have dinner, so I am telling you this. Out of the door, right. On the next junction turn right and go along the channel till you see the tram tracks. Then turn right again, and go about 100m - you will see several different restaurants.
The hostel looks and feels like it needs repair. Door knobs are almost falling off. The rooms are on one floor, the bathrooms and showers are on the other floor. Kitchen is a mess. The hostel located on a street which runs very steep up the hill on one side and down the hill on the other. If you have to go to Taksim square, where you can take a bus to airport and a metro to other parts of the city, you should go up the hill.
