We've had a wonderful time at Hülya's place. The apartment is comfortable, spacious, and looks even better in person than in pictures. The view is truly amazing. It's perfectly located it Cihangir, close to Taksim, the Bosphorus and most of the main attractions. The neighborhood is quite hilly (as most of Istanbul), which we found charming, but make sure you're okay with walking upwards a bit. Hülya was a great host, very helpful and accomodating. We'd gladly stay here again when visiting Istanbul in the future.
