Good place, quiet (the specification on the site, that there are constructions in the area seems not to be a problem
anymore), grea great location, comfortable bed, great shower, very nice staff in the reception (drop off luggage possible).
Overall good, specially if you come to Berlin on a work basis.
The only issue was internet! unfortunatelly, although discussed with the reception, no improvement.
There was a very poor connection all over the room, i could only manage to log in trough my own internet provider in the balcony (only!) and from there, connect my other device ( Laptop) trough Hotspot which also got dissrupted.
