Grunerlokka is a very young suburb just on the outskirts of Oslo CBD. The vibe is fun and lively, and only about a 15 minute walk to the city centre. Finns apartment is great, quite small but perfect for 2 people, and is amongst an apartment block which seems to be full of young professionals and families. Check in was easy as you pick the key up just around the corner, the only problem we had was finding the door to the flat as it's not very well signed, but if you look out for his name on a little print out, you'll see! Would highly recommend Finns place, was a very enjoyable stay.
