I love Turkey. However I do not think that this is the way how you can get any useful information. You will just get some twitter-like horrendous stories of scams and people who spent there several days/weeks and did not get to know the culture or even several turkish words at all. As for cost of living, visas, healthcare, you can find this info objectively using google. The rest - subjective stories, will be IMO just typical stereotyping DN trends, like Chiang Mai is best, Bali is not what used to be, Lisabon is top etc. These are just fads. I do not like Lisabon and like e.g. Tunis, where 99% of DN will never come. I believe the only way is to come to the country and experience it. Again, I can only tell from my experience that I consider Turkey to be one of best option for DN (me being from Central Europe = even travel time is very convenient from Europe)

I strictly oppose. Being from Central Europe, I have been to 20-30+ countries and Turkey cuisine is definitely one of the best in the whole region - mix of otoman, arabic, balkan, greek and many other influences. Only Chinese cuisine (or Italian) compare IMO. The best think is that Turkish foods are simple - we are not speaking here about hote cuisine, but simple perfect foods - street food is wonderful (e.g. simple pilaf). The only reason why you have so different experience IMO can be that you were somewhere in touristic places, where there are no actual locals.

People are absolutely friendly and helpful, even in metropole like Istanbul. In less people-heavy places even more. In villages - they will just take care of you. I do not understand your experience.

How long have you been/were there? It seems to me one week trip to Anatolia hotel chain or something like this, sorry.

I do not understand much the part “our country does not allow us to have a mailing address”. You probably mean setting permanent resident address (as mailing address is easy to get - you can use your family/friends/parents address to be mailed), so that you could prove your address to a bank. Actually, it is interesting. I am from Czech Republic and permanent residence is not at all connected with how long you stay there. If you are not staying for majority of year in the country (or you do not stay here at all), you are not even legally bind to pay taxes (or some of them), you do not have to pay social security/health insurance etc.

So what you mention might be some Netherland special thing. Actually, in Czechia you are obliged to get permanent residence due to law, so even homeless people can ask their municipality (or place they had permanent residence for the last time) and they just get permanent residence = address as their municipality (usually city hall address). Which of course does not mean they have right to live there. Right to live somewhere and permanent address (place of residency) are to different legal things in Czechia. I believe it will be very similar in many other countries. Did you really consult it with some lawyer in Netherlands? It might clarify things more.
