First of all sorry that i am not using german language over here but i've got a pleasure to people from German.

Well, me and my friends are going to Berlin for Bring me the horizon concert but we have no idea where to get some cheap and good hotel/motel/hostel or something where we could sleep, can anyone help?

I used my mighty googly skills:

What about Ibis hotels?

What about Ibis hotels?

 

Yeah, i have been in two of those (one in Cologne and one in Hannover) and they're quite cheap. If you don't need much comfort, it's fine.

A&O hotels/hostels are cheap too, but also not comfortable at all. (Have been in one on the reeperbahn :>)

 

EDIT: ibis budget Berlin Ost is 39€ per night (double room). (i have chosen 17.- 19.05. as date, since i guess you'll be there somewhere in that timeframe, seeing the concert is on Saturday 18.05.)
