The confirmation of booking came two and a half hours after my request with a help of Airbnb support.
Anyway, nice, comfortable, newly renovated house with fantastic home parfumes. The silent place is on the top of the hill where you can see the whole Oslo. There is a free parking place on the nearest street. The only two things I needed were not there: the WiFi (my kind request for the password was declined as not secure for the host) and washing machine (i asked for it but has never got the answer). However those options weren't in the list of services on Airbnb. Unfortunately, I never met the host and even haven't got the good bye words in the end.
The summary: it was good to stay there.
