GREAT location! Very easy to get to the central of Oslo by public transfer.
The rooms aren't sound-proof at all though! The neighbourhood itself is really quiet, but there was definitely some noise coming from upstairs. Not great, but definitely not a dealbreaker.
We couldn't use the kitchen (Covid, so temporarily), but Elise made sure that we had everything we needed to cook downstairs.
Also: prepare to meet the happiest and most affectionate dog you've ever seen before in your life!
