I stayed 4 nights in Marthe’s lovely home and had a great time. Her apartment is in a great location - for both getting around the city (I ended up walking everywhere) and to/from the airport with both bus and train options close by.
Her place is very clean and tidy with all bathroom and kitchen amenities provided. I ended up using the kitchen a bit as eating out is expensive in Oslo, and found it to be very well stocked. The bedroom is quite small but I found it to be 100% fine for a single traveller. Communication with Marthe was always prompt and the check in/our process was quick and smooth. Marthe also let me store my bags there the day I left as I had a late flight - which was much appreciated!!
Marthe is a great host and I will stay here again if I come back to Oslo!!
