Sergii and Tetyana are great hosts.
We stayed for a month with our 2 cats. The house was very comfortable. Great beds and well equipped. The house is in the middle of the street, and the neighbors are friendly, but the surrounding neighborhood (at either ends of the street) is not great.
When I read the description and reviews saying there were a lot of stairs, it just didn't sink in how many there were from the street to the 3rd floor (50). This house is not for the faint of heart - however, I lost 6 pounds this month!
