We enjoyed our stay at Nina's flat. Communication prior to arrival was clear and friendly. She met us at the train station despite it being late at night. She had prepared a variety of useful things for our arrival.
The flat was about 10 min walk front the station which wound past the opera house and over the water- very pleasant. Convenient to local amenities with a supermarket in the next building. The nearby restaurants also proved to be nice.
The flat itself was accurately represented by the photos and quite lovely. Excellent view from the balcony. Comfortable bed and bedding. Plenty of towels. Nina had been thoughtful enough to provide high-end shampoo and soap. She even had an umbrella for us to borrow.
I would recommend this flat as a base for a stay in Oslo. Nina was an excellent host.
