Great location! Really close to oslo city, just around a 20 min walk and great transport links right outside the apartment.
Can get to museums quickly and easily with the transportation links and vigeland sculpture park is a quick walk away from the apartment.
The only negatives really are that kitchen is very small, so only one person can really be in there to cook/ wash up at a time and because of only having two plugs in the kitchen and the fridge having to be on at all times, so you can only really use either the hob or microwave at one time.
