Norway in Mid October for 8 days

Me and my wife are planning to visit Norway in Mid October for 8 days. We are both in 20’s and love to travel. We are interested in exploring the cities, mountains and fjords. Our budget for the trip is around (€1000 - €1500) per person (Including flights, Accomadation and food).<br><br>So here are my questions, <br><br>1. What are the places that we can cover in 8 days. (We are planning to visit Oslo, Bergen and the fjords) <br>2. Is mid October a good time to visit? (We are from India, so we are used to warm weather) <br>3. How much are the flights to Oslo from Amsterdam (We are in Amsterdam currently) <br>4. Is Airbnb safe and affordable?<br>5. What are the good restaurants to eat at in Oslo and Bergen?<br>6. Is there any public transport card or any travel card that can be bought for 8 days (for Oslo and Bergen)<br>7. Our budget is around (€1000 - €1500) per person for the trip. (Excluding the flights) Do you think this budget is enough for 8 days. <br><br>Thanks in advance for all your answers :)
