This is not a hotel you should stay at, especially not on hot summer nights. And the reason for this is: for some strange reason the rooms are not equipped with convential curtains. Instead there are som kind of wooden "doors" to pull over the windows, making it impossible to have them open at the same time.
And as the rooms don't come with an AC-system either, your choise for the night is either to let all the noise and light from outside flow in, or simply being "bolied". There is also only one restaurant nearby, who serves lovely asian food, but have lousy service. The bakery just across from the entrance of the hotel though, was a pleasant surprise; they serve really good breakfast and cofee. Another plus, is that the S-bahn is just by the hotel. The room was spacious, and the refridgerator was also a plus.
