Hi all.
The location of Jamshid's flat is very handy. Close to various main roads with bus stop, grocery shops nearby and for people who enjoy to walk like me, close from Sentrum ( 30mn walk, Oslo is imho small beautiful city).
I stayed 6 nights there, quiete area. You have one room for you and share the rest of the flat with Jamshid and another person from his family. It can be confusing sometimes but I'm fine with that. You can go in, go out at anytime as long as you don't do too much noise.
I'm very pleased by my stay as I needed a place to safely drop my luggage and able to rest and to be clean as well. Mission accomplished. For people looking for a place to gather with friends, I think it's not appropriate as it's a guest room and you have to be respectful of your hosts. So I strongly recommend Jamshid's place for use case like mine : drop luggage and explore the city.
Have a good stay there and have a safe and good stay in Oslo.
Cheers.
