Just stay here, it is the best hostel. Staff is really friendly and nice, and every night you go out like a little family, it is a small hostel but its the best, it makes you fell like home.
We had a great time there, it has a great location you can meet a lot of people there, very clean and cheap, definitely the hostel to book in Berlin.
Everything was perfect, it was a little hot so a fan or ac would have made it a lot better, keeping in mind the price per night it should have been included, anyways we had a great time. Would stay there again.
