We had a nice stay in Nicolas Apartment! The communication and the Check in was really friendly and easy. The area of the flat is perfect and you have got all Public Transports 2min away. The one room Apartment is perfect for a couple, but also with 3 People it's enough space. The only negative thing were the thin walls in the apartment. But all in all we had a nice time in Oslo and would definitely recommend a stay in Nicholas Apartment!
