Pros:
Great location (literally across a u bahn station
and bus station, walkable distance to main district)
Seamless check-in
Clean and comfortable room
Good communications with customer service team via ws
Cons:
Unfortunately wifi didnt work throughout my stay, but the customer service team has been quick in responding to my message and offer compensation to the inconvenience
Never been able to find a rubbish bag in the laundry nor garbage room, so i ended up using a paper bag i got from a shop as a rubbish bag for a week
All in all, a good place to stay in Berlin considering the great location and comfort.
