Heidi's instrictions were clear, the apartment description is acurate, the neighbourhood is really nice. There's a tram stop within 100m, the apartment is on the 4th floor and I did not notice any road noise in the apartment.
There's a loveley little balcony to the rear, from the kitchen, unfortunately the temperature was close to freezing so the only thing I used it for was cooling beer (there's a big fridge - but the balcony was more quaint!)
If you are looking for a sterile, lifeless serviced apartment then this is probably not for you. Instead Heidi's place really is home from home, the kitchen shelves are packed with Heidi's food, the coffee table is laden with art books. It seemed like Heidi had just popped away for the weekend. It's a self-clean rental that Heidi operates, so that makes it feel even more homely and lived in and less disenfectant cleansed like some serviced apartments. By the middle of my two weeks it really felt like a 2nd home to me.
Thanks Heidi for renting your home to me, it made my business stay in Oslo so much easier than in a hotel
p.s. it was far from cold - there were t electric radiators and with them both on low it was more than warm enough (and I really feel the cold - after reading previous reviews, I brought wool base layers and a Rørus blanket!)
