Response from Aleksey:
Taking into consideration that host left in the flat garbage by himself (box of empty bottles, pack of garbage in the balcony and in the bin), and that we lived there for 3.5 days, 3 packages of garbage I think is normal, especially, when we sort plastic, paper and other separately. We did not expect hotel standards from the flat, we stayed in 8 flats in Europe this time, and this place was the worst one. This feedback from Bjoern is revenge for my bad feedback re his flat.
