Hilde is an extremely helpful and accommodating host who was on hand to make suggestions of places to go and see and how to get there. We spent 3 nights happily there at the end of our holiday.
Hilde has a very unique apartment which was very clean and comfortable to stay in. The roof terrace has a lovely feel and a different view of Oslo and although the balcony isn't large it was still a cosy place to sit with a coffee. There was plenty of space for us, a family of 4, with my son taking the second bedroom and my daughter choosing to sleep on the sofa, though another mattress was available to use. If you struggle to sleep when it is light it might be worth taking sleeping masks, but that wasn't an issue for us.
As Hilde's apartment is on the 5th floor it may be worth taking up a couple of basics such as milk to be able to make a drink to settle in though the 7-11 is only a couple of minutes walk away.
The location was great as it was in walking distance of the Frogner Park and the Vigeland Park within it and we also walked to the Royal Palace which took a bit longer. It is also only a couple of minutes to trams and buses and Oslo's public transport system is very effective.
A good idea would be to install the #Ruter Reisse app which showed us how to travel between locations easily and which public transport to use. The #Ruter Billet app allows you to buy tickets as well though if you are planning to visit a lot of museums or do a lot of journeys it would be worth thinking about buying an Oslo Pass.
I would suggest, as there is no lift, that you would need to be ok with climbing a lot of stairs to stay here but if that is not a problem then you would certainly receive a warm welcome from Hilde.
