I spent 8 days in Deniz's apartment, and it made a perfect base for exploring the wonders of Istanbul. The apartment itself is a stylish mix of old and new: modern without being corporate, and with enough vintage flair to keep things warm and interesting. Every element shows clear thought and design intent ... and the bed is very comfortable too.
Likewise, the neighborhood is a great spot. Winding cobblestone streets will take you down to Istanbul Modern art museum and to the tram or up to Galata Tower, metro, and Istiklal Cadessi. Walking to Aya Sofia and the Blue Mosque across the Galata Bridge was easy and pleasant, and it was simple to take the tram on longer excursions. In the neighborhood, every street holds new and interesting coffeeshops, galleries, antique stores and more.
Deniz was very helpful and always immediately available by text when I had questions. The listing is very accurate (though it looks better than in the photos!), and I would happily stay here again.
