We stayed at Oleg's apartment for 8 nights and it was a very good experience. The place is very spacious, clean and gives you a homely feeling. It is pictured very correctly, I found exactly what I expected.
The neighbors are lovely people, the place around is calm and feels very safe.
Unfortunately we have not met Oleg, but his lovely neighbor Greta showed us in and explained everything, besides Oleg left very clear guide in writing. Communication with him was easy, friendly and nice.
I'd recommend his place to everyone.
