Nice hotel; especially after experiencing two more hotels in other parts of berlin. This was defintely the best. Liked the fridge, coffee/tea facility, free minibar, tasteful design and comfortable bed. Moreover, location is great. Friendly staff and liked how everything was automised and easy accesible. Great communication via whatsapp when having questions.
Minor things to improve: our sunblock screen didn't work (seemed like it was only a problem for our room), chromecast had issues and didn't work, lights are rather dark, especially where the mirror is. It was great that they have lockers to store your luggage all day after checking out; but be aware to take some spare time, since we were not the first ones having issues with opening them again. Might take up to 20 minutes, since there is not always somebody on site.
