We had a wonderful time at Emirhan's apartment and highly recommend it for long or short stays in Istanbul! We loved waking up to the view of the Bosphorus every day and found the apartment perfect for our month-long stay. The kitchen was filled with all the appliances, especially for modern Turkish life (such as the çaydanlık, or double teapot) and a Turkish coffee maker. The bedrooms and bathrooms were well furnished and we were very comfortable. The location of the apartment is a real win -- walkable to Beşiktaş, Nişantaşı, Galata and Galataport, but also super close to the Metro, the tram, and the funicular, the apartment was accessible to almost anywhere.
As other reviewers have mentioned, the hot water runs out quickly, but this can be remedied by turning the shower tap to the left until the hot water returns. There are a few step stairs at the beginning and occasionally the neighbours are noisy, but these are minor complaints. Overall, highly recommended!!
