Most important thing to know: This is not a real airbnb, it´s a hostel. The host has a couple of houses in the city and rents out the rooms, but they live somewhere else. We barely got to see him, he also didn´t show up when we arrived, so the housekeeper welcomed us. She was super sweet and more around and communicative than the host. Also the rooms are photographed from a very good angle, our room was not "huge" as described and sleeping in there with 4 people would have been a desaster, especially because 2 of them would not have a proper bed.
I´m super glad we didn´t get into the tiny room upstairs, which looked nice and cosy in the pictures but is actually a windowless closet.
The rooms and kitchen are clean though and the house is very well located. Its possible to go to the center by foot and there´s a supermarked close.
All in all it was alright to stay there but its a hostel atmosphere and because of the pictures that differ from reality it feels like a rip off which wouldn´t be necessary since the house is nice...
