As other guests had noted Oliver was very good on communication and a quick responder.
My wife and I arrived at Oslo airport in the snow and it was cold outside during our week's stay (last week of November 2022) at Oliver's convenient ground floor apartment. Inside the apartment was warm and the showers were excellent, which is just what we needed in winter. The Sagene location was very good for us as we were visiting family nearby, furthermore local shops, coffee bars and restaurants were plentiful and good. Easy to get to the frequent 54 bus closeby (15 mins to centre) or even the tram across the river in Torshov for a different perspective. We considered Oliver's place would be at its best in the summer months nevertheless it was a good quiet location for us, thank you Oliver.
