We stayed for 2 nights at Sara and Hannes place, and it was very comfortable. The pillows are really soft, the apartment is warm and there's no trace of damp anywhere, there's a big bathtub with excellent water pressure. Good Wi-Fi. There is no TV but we didn't actually need one. The underground is very close by.
Hannes was very responsive and helpful with tips and even accommodated our very late check-in!
I am glad to have stayed there and will book again.
