Martin was incredibly friendly and helpful. He kindly picked us up from the train station and even gave us a lift back the station when we checked out. The apartment was even better than it looked on the listing. It was clean, cosy and modern. It had everything we needed including a few extras. The bed and couch were both very comfy. The heating works quickly and is easy to use. The floor in the bathroom is also heated. The cable TV is excellent and has lots of channels. The apartment complex is really smart and has a lovely roof terrace with views of the city. It is also incredibly secure and in a quiet area despite being so close to the city centre. It is 10 minutes walk from the opera house and there is public transport 5 minutes away. I cannot recommend the apartment enough, we plan to stay there again when we visit Oslo in future.
