Very, very pleasant stay. Although the flat is quite far from the centre of Oslo, the metro (T3, Ullernasen) is a 5 minute walk away.
The flat is spacious, pleasant, clean, we were mainly 2 on the 80% of the stay, but there is largely place for 5 :)
Possibility to enter the flat with a digital key, which allows (in case of a rental for 4-5 people) not to have the worry of having only one key.
Jason is very reactive in case of questions. Everything was perfect
