Location, location, location! The place is located in a quiet, super-central neighborhood with everything in walking distance. You have a grocery store in the underground floor of the building, which is super convenient, and right around the corner you have the public transport, which can take you wherever you need. There are many restaurants/bars/cafes/parks/skate parks and a cinema, all within walking distance.
Natalja is the host of all hosts, super polite, flexible, accurate and ready to help with everything one would need. Communicating with her was easy, quick, straightforward and pleasant. Please consider her list of places to visit, and foods/drinks to try - recommendations are spot on!
The place itself was as clean as it gets and all the amenities were in excellent condition. The flat is everything a single person, or a couple would need for a great stay in Oslo!
