Nice things first: The communication around the reservation process worked smoothly and quickly, picking up keys and finding the apartment was easy, too. The very basic amenities were available, though guessing a handwritten and washed wifi code proofed difficult, yet possible. The neighbourhood is what it is, no complaints here, choosing Hermannplatz means getting it.
Yet, to be honest, the degraded continuation of Hermannplatz neighbourhood inside of the house was an adventure, to put it mildly. The dirt was unbearable, drain clogged, the washing machine smelled foul, messy corners everywhere, moldy vegetables in the fridge and animal hair all over. I booked a stay for Friday-Monday. Friday - Saturday I was very busy that i only spent time in the house during darkness and with open windows, yet Sunday-Monday sun and cold weather revealed in full spectacle what wasn't even attempted to be concealed. I feel embarrassed for writing this kind of harsh review, which still doesn’t accurately translate into words the situation I found.
I believe it usually is fair to sort things with a host and not make public minor complaints, but here it would feel unfair towards potential, future guests.
