Communication with Daniel went really well, he has been a helpful host. He recommended a lot of places for us to visit and was not shy regarding giving us tips on practical information as well as experiencing the city. The location is central and fairly close to trams and bus stops that lead to all the places one should experience when visiting Oslo. For such a location, the price was inexpensive and spot on.
(The only thing I have to remark on is the cleanliness. There was a lot of dust and I suggest that it improves. In my PERSONAL opinion, this is not that big of a problem, but as an experienced host I know that there are a lot of people who find it important. My family found it more important than I did.)
Other than that, lot of thanks to Daniel for hosting us! If I return to Oslo, I'll check in again.
