Mona's place is as described and was perfect for my week's stay. Having been to Oslo for work many times before, this was a nice, cosy and quiet respite from the usual hotel! Although I never met Mona in person, she was very thoughtful and accomodating via email. Instead I met her husband Roy & ran into him on several occasions and he is also very nice & hospitable. I am a big fan of Grunerlokka so the location was perfect, with nice parks and the river close by; with easy access to the city centre either by walking or public transport. I hope to be able to stay again sometime! :)
