We just stayed at Nils' appartment in Oslo for 4 nights, and I can only agree with Nils' other reviewers.
The apartement is immaculate. Very clean, brand new and in a great location surrounded by bars and restaurants and right next to the Astrup Fearnley museum. Bedroom is pretty small but still has enough room to store your stuff; the bed is very comfortable. All perks are as advertised; Wi-Fi works perfectly.
Communication with Nils was flawless from the beginning. He was very uncomplicated in catering to all our needs and making us feel welcome.
This was our first airbnb experience, and an ideal start to hopefully many more!
