Firstly, the entry: Was very good, although I arrived late in the evening in Oslo, and he then also had to go on. But we managed to hand over the necessary keys to me.
Location: In fact, very accessible and also only in 30 minutes very good to reach by foot (a lot of straight walking from downtown). Alternatively, you can also reach the apartment very comfortably in about 15 minutes by public transport (e.g. bus no. 34 and 54) via the bus stop near Oslo Sentral.
Host: Ahmet is a cool guy who adapted very well to my late arrival due to bad weather. Besides that, we got along fairly well.
Facilities: Everything I needed was there. I was out of the house most of the time anyway, but everything was mostly clean (except for a few spots on the windowsill for instance).
Toilet was fine, and the bathroom was also good to use, although both were kinda narrow in some parts
