We had a short but lovely stay at Rennveig and Johan's apartment. They were extremely friendly and helpful and contacted us before our stay with excellent advice and directions to reach their apartment. They also gave us good advice on places to visit and eat in Oslo which we would have not found otherwise. They were very approachable and happy to help us with any queries we had.
The apartment itself is exactly as advertised- a semi detached annex comprising a kitchen/sitting/dining area, a shower/toilet and an upstairs bedroom with a very comfy bed. The neighbourhood is really nice and tranquil. There is an excellent bus service which runs approx every 10- 15 mins to the centre of Oslo (about 10 minutes journey) and is located about 5 minutes walk from their house.
Overall we had an fantastic experience and only wish we could stay longer- if we return to oslo, we will know were to stay!
