Location was perfect for restaurants, bars, public transit, and parks. Everything you could possibly need was only steps away from the apartment. The main street can be a bit noisy on the weekend nights, but it the apartment is on a small side street so the noise shouldn't bother anyone with the windows closed. There was a small festival going on in the park next door which was great and the food and cafes were amazing in the area.
The apartment itself was well decorated and comfortable. The heated floors in the bathroom were a nice treat (even in the summer).
If we come back to Oslo, I would definitely stay at Julian's place again!
