I rented the appartment for a whole month.
At first day, I did not receive check-in instructions until I called the host. First she told me she had to send them to me by email, but she was not so after my second call to her I got them.
The biggest grievance was the lack of communication with the host. It takes several days to answer simple questions or sometimes the host does not answer at all. Very annoying.
For example, I was waiting for very important mail from local tax administration and asked for the host to check out the mail box, but didn’t answer my request..
Also there was a kitchenette in the apprtment but only one of the two Stoves was working. When I mentioned about it and asked if it could be fixed, nothing happened. So for a month I only had one working stove and the host did not take care to take care of it. There was no dish brush or anything else to take care of day-to-day cleaning.
This appartment might be okey when you're visitong only a couple of days / a week in Oslo but for a longer period of time I would highly recommend any other option, this is not worth of money and this is entirely due to the indifference of the host towards the residents needs.
