Hello from Istanbul!

I am very new in the forum, but it looks facinating. You are anwsering all questions and helping everyone. This is great!

Now I need your help and suggestions.

On 5-7 May 2000 will fly to OSL from IST with a Lufthansa FlySmart Award Ticket. I will stay in a friend's home. I will have only two days to visit city.

05MAY00 LH3481 ISTFRA 1810/2015
05MAY00 LH3102 FRAOSL 2145/2340
07MAY00 LH3117 OSLFRA 1840/2050
07MAY00 LH3470 FRAIST 2135/0125+1

Where should I visit? Where should I eat? What are "must"s in Oslo???

And my connection time in FRA is only 45 min. on the way back. What if my OSL-FRA is delayed in OSL? LH will book me on Monday morning flight and give me hotel, right? Or no hotel because my ticket is free??
