Excellent place to stay. It’s even more central than described, at St. Olavs plass, perfectly situated between east and west Oslo, and just 10 minutes walk away from the sea. It’s neat, compact and perfectly clean. Very well organised with codes instead of keys. I’m from Oslo myself but I don’t live here now, and I totally enjoyed coming “home” to an old (very well renovated) building with tall ceilings. It’s really small, like I tiny apartment, but you have everything you need to feel comfortable and safe. Its like a little hotel and you don’t meet the host. I recommend.
