"Service to the room was irregular- there were days the coffee and water were not replenished (3 days in a row at one point) and the electrical was odd - lights that wouldn’t switch off (had to go to the front desk) or that wouldn’t turn on.
However I happened to be there on my birthday and the hotel surprised me with a card and lovely cake - they clearly got my birthday from my passport at check in. So that was lovely.
Convenient location close to S and UBahn, and there’s a grocery store across the pedestrian mall if you want to stash something in the room’s bar fridge."
