The room was booked around 21:30 the day before and Sonja responded very quickly; fast responder.
Very nice room with WIFI, TV, computer screen, very nice bathroom and parking on the property.
The room is very clean and looks new; It has everything needed for a stay, even a kettle and a small espresso machine.
The house is a little outside "downtown", but still near with transport. Bus and metro are nearby and give you the chance to already see something; you'll be in the city in no time. There are also e-scooters everywhere that can be used.
I would say ⭐⭐⭐⭐⭐
For Oslo and non-EU guests: consider getting a EU SIM card, since practically everything is done by mobile phone (bus tickets, e-scooters, food, etc.).
