Oleksandra is very nice and helped with any issues we had during our stay. I was with my wife so I thought the room was a bit small for 2 people, but should be great for 1. It has a chair and table which were useful for me to work.
The apartment is located a few blocks from the subway stations so it's easy to go anywhere.
Some small issues we found are:
There is a loud noise from the toilet pipes (which is just behind the bedroom) that was flowing every 2 or 3 minutes, so every night I had to close the toilet handle to be able to sleep.
The description didn't say anything about not being able to use the stove, but we were prohibited, although she let us make some noodles. Also it said we could use the washing machine if staying for a week or more, but when checking in she said we had to pay 5 euros per use.
