No Free airport shuttle but there is a free way...The shuttle bus that runs between all nearby hotels & airport will cost Nok 80 (7 Euro per person,May '24 prices). But please take the government bus 420 from the airport will cost 42 Nok(3.80 euro pp),the stop is on the main road about 80 meters from the hotel entrance.
I travelled for free by using the 24 hour day pass from ruter app( remember to purchase zone 4 or if you want to travel only between airport and hotel or buy from zone 4 to zone 1 ,that covers all over Oslo including tram, train and ferries.Zone 1 is Oslo city area).
Zone 4 to Zone 1, a 24 hour ticket will cost you Nok 124( euro 10.90) which will cover all your transport needs in Oslo for 24 hours under 11 euro!,great Value.Taxis are costly in Oslo ,so as everything else!!!
The hotel is basic,not luxury,good for a transit stop or if you are on a budget.
I paid euro 86 per night for 2 people ( 43 pp/ per night including breakfast).
Self check in possible.
A very good breakfast served from 4 am.
No daily cleaning, they clean on the third day only.Only Extra facility offered is Gym and sauna.
Tip: Request for a room with runway view, it's very close to the runway,you can see almost all take offs, even they have benches and tables for plane spotters at the back of the hotel.
