We had a one night stay with John although we did not meet, as he was away at the time. John gave clear instuctions on key pick up and we found the apartment ideal for our needs during the stay in Oslo.
We were of course unsure of the area & places to go, which we are sure John would have provided if he was there, so a useful idea (unless we did not see it) would be recommendations in a folder for places e.g. suggested restaurants etc.
Overall a nice apartment and convenient location.
