Singer Hostel Berlin is way better than how it looks in the photo shown in the listing. It is extremely clean and comfortable and feels just like a hotel! A Canadian roommate and I agreed that this is probably the best hostel we have ever stayed in.
The Odyssee of the Hostel lets you rest comfortable and charge your devices while you wait for your time to check in. Connor who mends the reception is extremely friendly and helpful. There are also toilets for guests before you check in and after you check out. It's basically everything you'd expect in a hotel.
The room is so clean that I have no issue walking around barefooted. It's so spacious and comfortable that my roommates and I didn't mind hanging around and chatting in the room. The toilet is also incredibly clean and there is also refrigerator in the kitchen.
The hostel is located near the S-Bahn station and is convenient to get around to the main attractions in Berlin. Wifi here is also stable and fast, which helped me greatly because my 3G doesn't seem to work in Berlin.
I enjoyed my stay so much that I'm sad I'm only here for a night. I would definitely recommend anyone who's visiting Berlin to stay in Singer Hostel Berlin!
