The room available as an Airbnb is a nice little cozy room, which I believe Marina uses in weekdays as her workplace, so you might see in your room some stuff like sewing machine and all, which didn't bother me.
There are two single bed in the room, and a big table which you may use as a dining table.
Everything was great I believe, except that I was under the impression that the kitchen and bathroom are separate for us, which was not the case. Its not a major deal breaker, but it felt like barging into their personal space if I wished to cook something in their kitchen, which she offered to though. Also the bathroom has got no locks, but just a sliding door, which I understand is because they have a cute little kid in the house.
Overall, it was a nice stay and would recommend it.
