The place is located in a new stylish area right in the center of Oslo! Only 7 minutes walk from Central railway station. Windows are going into the inner yard, hence the noises of the streets won't disturb you at night at all. It was very easy to communicate and receive the keys from the apartment (we have actually moved in early in the morning, before the "official" check-in time, as it was more comfortable for both of us). On the way to the apartment we were shown the local shops and got a brief description of the area. Some parts of the area are still at the construction stage, but yard of this apartment is completely finished and it's well away from not finished parts. The building is very new and has all the hi-tech things - you can control ventilation and heating level, cozy balcony is a plus. You can use washing machine inside as well as dishwasher.
Overall - great place to stay, highly recommended!
