This is a great apartment in all respects which allowed us to make the most of our 4 day stay in Oslo. Its exactly as described with two separate bedrooms, the smaller of which was perfect for our 15 year old. It's really quiet as it is at the back of the apartment block. The little balcony with a view over the garden was great at the end of a long day sightseeing in the Oslo "heatwave".
The location can't be faulted. It's across the road from the park which you can walk across to reach the botanical gardens and museums there. Best of all it is just round the corner from trams 11,12 and 13 which take you to the city in 5 minutes. Within a few blocks (minutes away), there are heaps of vintage and retro shops. The ordinary necessities are also close (on the same street as the tramline). There is a good fruit shop opposite the Deli de Luca and a supermarket on the other side of the the street (half way up the block). There's also plenty of bars and some reasonably priced restaurants. The kitchen is well stocked though so you can eat in (and enjoy the balcony).
Gry was a great host - she answered all questions promptly and her instructions made it really easy for first time Oslo visitors to find her place. She even left out some provisions which really made us feel welcome.
