I stayed two nights by Sachin and there were very positive parts about my staying there: the place is very close to the city center and has easy access to the public transportation. It took me a 19min walk from Oslo central station to Sachins. The communication with him was really good, he was always kind, really fast at answering.
However, there was also negative aspects as floor in the room was dusty and people won’t have access to a kitchen. I normally don’t need a kitchen but I can understand that some people might want to have the access to that as well.
Important points people should know, you’ll hear his kids from the bedroom while they’re playing or having conversations, so if you’re not a kid-friendly person maybe you should reconsider your staying. Also the apartment has a special smell and if you’re very sensitive in these terms maybe also reconsider.
I can honestly say that for over 100€ I have definitely gotten better deals, but no regrets staying here: I was alone, felt safe and had everything in a walkable distance and those are the most important aspects when I am traveling alone.
