The room was clean.
Many things were thought out well, while others were poorly thought out. Overall the room is not bad and my arrival was pleasant, but there were a number of cons. I hope the owner would be interested to improve future stays.
So,
1) the kitchen missed some essential stuff for cooking.
2) wifi connection was poor, as the room is located far from the router, I guess. TV didn't have the connection as well for the same reason, I presume
3) I missed some pieces of furniture where I can eat. Nothing except the bed to sit on.
I had good experience of communication with the owners. (No contacts, just via texting in the app) It seemed to me they are ready to make their guests more comfortable.
They hospitably provided me with the coffee-press and the sponge (to wash the dishes) that I had asked for. I hope they can easily improve the accommodation so that I can say that the room is in line with the price-quality ratio.
I can not give more than 4 for now.
