It's a house with multiple lockable rooms where guests can stay.
I liked that the kitchen was self-service. There was lots to choose from for breakfast. We also used the refrigerator for our own stuff. There was a big supermarket 150 meters from the house and a McDonald's even closer.
Check-in was a bit strict, just 13.00 to 14.00. The host may be more flexible with the times if you call them well ahead of time but our flight changed schedule to arrive three hours earlier than expected, so we waited at McDonald's for two hours and we still had to call the local number when we got there (though the host was just a few minutes away).
The house was located in a somewhat busy junction, so there was noise from traffic.
The location is somewhat far (around 5 km) from the city center and also quite far (1.4 km) from the closest railway station that has a train to the city center. You can't buy tickets on that station, so you need internet to use their app, and the trains don't go very often.
The sink had two separate taps for cold and hot water.
