The Singer Hostel boasts great facilities and an extremely helpful staff. The sleeping rooms are comfortable and clean, with great common areas to lounge in. The location is extremely walkable to the inner city, and conveniently located by train from the airport. The only downside is the neighborhood may be a little intimidating if you’re arriving alone late at night, but it was very navigable and we had no reason to feel unsafe. I would recommend the Singer hostel & Berlin to everyone!
