The Grand Hyatt, while a bit in the older side, is a highly acceptable and comfortable option for Berlin. Conveniently (though not centrally) located, it is walkable or a short ride to anywhere in central Berlin. Rooms are mostly updated and maintain standard expected from Hyatt. Only some small details, such as TV not mounted, lamp cord hanging down wall, etc. Not a big deal at all just small details. Bathroom was excellent, go for the city view not Courtyard, breakfast buffet quite good. WiFi speed acceptable (about 4-5 megs). Very friendly staff, nice lobby bar.
