Super stylish, amazingly helpful...
The flat is as good if not better than the pictures, very luxurious, thoughtfully set up with top notch appliances, amazing bathroom, books etc. Jonas (who designed the place) was unbelievably friendly and helpful, he organised airport transfers, gave us maps for local bars and restaurants and even helped with a bizarre shopping request - sorry Jonas!!
The area is the best in Istanbul for both tourist sites, and cool places to go out, soho house, junk shops, museum of innocence are all five minute walks. We loved it, and will be back!
