Pros:
1) The location is amazing - right in the center of a super trendy and modern part of Oslo next to the modern art museum, cool restaurants, and docks where Norwegians sunbathe and swim in the summer.
2) There's also a rooftop terrace with splendid views.
3) Jang is very responsive - I never had to wait more than a few minutes for a response - and was very pleasant.
4) She provided a simple free breakfast every morning
5) The bedroom and bathroom were super clean.
Cons:
1) There's a fee for everything, including early/late check-in, late check-out, luggage storage (but it's also only available if you can pick it up at a very specific time), and the house rules are many, many pages long with very specific fees for very specific things. The description "YOU CAN CHECK IN ANYTIME 24 HOURS /DAY EASY!!!:)" is misleading as it does not mention any fee.
2) There are signs in the bathroom asking men to sit while they pee
3) There were 6 total signs in the toilet including asking guests to clean the toilet with a wand and soap after use
4) Given all of the signs and hidden fees, it made the stay feel rather uncomfortable. I felt like I was staying with someone who was trying to extract as much money from me as possible, rather than staying with a knowledgeable and friendly local.
5) Check-in as after 4pm and check-out is at 9am, and there's a strict 500nok fee for check-out anytime after 9am. Also 9am is the earliest check-out I've ever had across any airbnb or hotel, and there's no flexibility with it.
