Irja's home is located wonderfully central. Nice shops and bars around, public transport and rental bikes just outside the door but you can walk to the city center in 15min too. The setup is basic but it has all you need to feel welcome and at home. Irja did a great job a letting me into her home and sharing even while she was not there - her coordination of the key handover worked perfectly. I can highly recommend staying here for you visit of Oslo!
