I had a great stay at Fehmi's place - the location is fantastic, just 5 mins walk away from the major sights of Sultanahmet, round the corner from a supermarket and lots of cafes and restaurants. The apartment itself is lovely and exactly as described - some other reviewers have pointed out that it's small but there is a big south-facing roof terrace with a table and chairs and amazing views so you can have coffee and eat your meals there. I thought it was the perfect space if you're travelling on your own but lovely for a couple too. The building was safe and secure and Fehmi was really helpful and even brought me some milk on my first morning in the apartment. He also arranged airport transfers which made a late night arrival and early morning departure really easy. I ran out of time to see everything I wanted to see in Istanbul - amazing city! - so I'll be back, and I'd definitely stay here again. Highly recommended!
