Last minute SE questions

[kanewai]

Four more weeks! And then I can start answering questions more than asking them!

I have 4 days in İstanbul, then 11 days for Diyarbakir to Antakya. I pretty much know my options, but still have some questions:

DİYARBAKIR
Two to five days (including daytrips and an overnight at Hasankeyf), depending on how I like it. Is it worthwhile trying to time my visit for the weekend? I love live music, and have some recordings of Kurdish jazz (fusion?) that are amazing. I also read that the birhane were closed; is that true?

TUR ABDIN
Has anyone here actually made it to Anitli using public transportation? If I have to hire a taxi, would Hasankeyf make a good base?

KARADUT
This looks like the most interesting approach to Nemrut Dağı. Has anyone stayed at the Karadut Pension?

URFA
3-4 nights (including daytrips)

ANTAKYA
2-3 nights (first day is all travel, so it doesn't count!). Some of my books don't even cover Antakya. The 'budget' places I see online are 40-50€! Anyone have recs? Or know about the Beytuturab-Toprakev?

I know that's quite a list - there isn't that much information out there!

(edited to remove questions on Savur and Midyat - the small hotels don't appear to be open during March)
