We come to Berlin 4 times a year since 5 years. Normally, we rent comfortable flats for 60 euros per night. Here, we rented a room for 3 nights for 250 euros, which is a big amount for Berlin (it was also Sylvester). The result is that you pay more for a room shared with 6 other guests, than a 4-star hotel... In addition, the sheets weren't fresh and didn't smell very good...
