My daughter and I stayed at Tove's house for 8 very nice days. It was just as lovely as the pictures and a beautiful location with easy tram lines right into centre of Oslo. You can also have some fantastic runs or walks in the parks all along the Akerselva which follow the river into the heart of the city.
The modern and beautiful apartment was a joy to stay in with a nice market and cafe's just down the street. It was a ideal base for our visit.
Unfortunately Tove as also travelling at the time so we did not get to see her but she stayed in touch and left many helpful instructions and notes.
