The staff's advice were not always accurate. The car park is only big enough for 3 cars and is always full so you can't rely on this. The facilities are clean enough
The hostel has a great bar with good music to have a drink and enjoy yourself at night but take your ear plugs with you if you're planning to sleep, you can hear the music really too loudly from the rooms.
This hotel didn't meet my expectations since the pictures are showing you a lovely hotel. In fact, the only advantage is the location in a particularly nice neighbourhood in Montmartre. I was particularly disapointed by the facilities. Indicating "ensuite bathroom" they mean toilets in the corridor and the shower alone (not a separate room) in your room.
If cleanliness is your priority, I definitely recommend you to stay at this hostel. Moreover the staff knows very well the town and is able to give you valuable information
The bathroom is far from practical but the atmosphere there is rather good and you can meet with very friendly people. They made a mistake with the booking but where nevertheless able to offer me a bed so that was no big deal!
The Circus is just a perfect hostel for your stay in Berlin! Very well located! It's really comfortable to have a bar in the hostel The team is really nice. What is amazing is that you meet so much friendly people from all parts of the world!!! I definitely recommand it!!!!
