Apartment and building is very secure with codes to enter into the gate, the building, the floor you’re on and the unit itself. There is no lift So if you are planning on bringing luggage on your stay, I would probably see if you can request a lower floor unless you’re OK with taking trips. The apartment was pretty small but it was just me so I didn’t mind. The bathroom is pretty small and has a shower, toilet, sink and washing machine so be careful with the water. It will get everywhere. The location is perfect for everything you want to do in Oslo and the bus stop is right outside that takes you to and from Oslo Central Station. There are also electric scooters like Ryde (pretty cheap) around the city and usually the building that you can take and get around in a small amount of time :) I will definitely rent again!!
