The apartment is clean and well cared for, with lots of thoughtful details that we highly appreciated - you can really feel that Katia wants you to be comfortable.
But there are some serious structural problems. Like location. It's more or less in the centre, but without properly functioning public transport, so we had to drag two suitcases to the train station on foot.
Another problem for us (both 1,80 cm) was the uncomfortable bed and bathroom that is fit for a dwarf, or maybe a child. The whole room is 2 square meters or so. In the shower, you can't wash yourself without sticking an elbow out of the curtain. The upper rim of the mirror above the sink finished on the level below our necks, so we couldn't see ourselves, and it was barely possible to wash our faces (the width of the room is not enough to bend over the sink). If you are a tall and/or large person, I think this apartment is a bad choice. Otherwise "ok".
