The apartment was clean and spacious. There seemed to be ventilators but they did not really keep the apartment cool (though this is typical in Berlin, I think). Problem #1: there was no shampoo or shower gel -- which is supposed to be provided. Problem #2: the sink in the bathroom only had hot water, which became boiling hot within seconds. Problem #3: In an entire week, the repairman never came; only a cleaner who brought shampoo and conditioner (which was already there) but no shower gel. Multiple emails sent to customer service didn't result in the faucet being fixed. We ended up brushing our teeth in the kitchen sink, which is fine, I guess. So: terrible communication from a distance (customer service seems to be based in Poland). However, if everything is fine in the room and it's not too hot and humid outside and you don't need anything, it's a good deal for the price and the convenient location.
