Circus Hostel is a nice place to be for your first few days in Berlin, mostly because it is located in Mitte area, and close to the main tourist and historical elements and locations in Berlin.
This hostel is in a central location, very close to a large junction, and a metro exit. As a result, most of the night it is quiet, and you can have a good night's sleep. During the day, however, loud noises are a bit disturbing, especially police and ambulance sirens, which are loud enough to wake up the late sleepers. Nearby there are a couple of restaurant and pubs -- some are open until late.
Rooms and Bathrooms
Bedrooms are of decent size, some with bunks and others with single dorm beds. A small locker is located above each bed. Each hallway leads to approximately ten rooms. The long hallways are all colored with multiple "circus colors," which might make tipsy visitors get lost on a regular basis.
Every hallway has its own bathroom and toilet, both are very clean. One soap device is located near each sink, but none in the showers. The main bathroom area leads to couple of small showers, each one with a lock. There is only a small space for personal items, with hooks and a small shelf in every shower.
The common spaces are a bit small, with a sitting area, a pub located downstairs, and a coffee place, with a door separating it from the lobby. The pub is open only at night, while in daytime the coffee place is open. In the lobby there are sofas, some regular chairs, and a few rocking chairs, which are very comfortable. The lobby is usually not too crowded, and if you get there on time you can catch the daily free tours in Mitte area, which begin here.
The security level in this hostel is very strict. You need to have a magnetic card in order to get to any location in this place, including the elevator, and the main entrance at night. The most absurd thing is that if you wish to use the stairs instead of the elevator you still need to wait for it to get to the ground floor, as the elevator separates between the stairs and the lobby.
If you are a tourist who wants to see the basic attractions of Berlin, this would be a good option to choose from the variety of hostels. Feeling safe and comfortable, you will enjoy the pleasant atmosphere, and feel almost like you are in a circus tent.
