We had an amazing time in Lines apartment. It is very cosy, modern and clean and you feel immediately at home.
The apartment is well equipped, you find everything you need and also several supermarkets are around the corner. In Grünerløkka are a lot of restaurants, bars and shops just nearby the apartment. I can really recommend to stay in this area and Lines apartment.
I haven't met Line in person but the communication with her was great. She answers very quick and is very helpful.
