The flat was in a very good condition as described, and Evgeny was really nice. He let us stay until 6pm on the day of check-out since he did not have guests checking in that day (lucky for us, maybe not for him). This worked really well with us to catch our flight after a good sightseeing on the last day too. This proves he cares about the travellers and doesn't see them as pure sources of his income only.
Thank you Evgeny, and I will definitely stay back there.
