Stayed with two friends over a long weekend. The apartment is in the hip Beyoğlu neighborhood of Istanbul with lots of cute design shops, music/instrument stores, a range of food options, cool bars, and the great Galata Tower (with amazing 360 view of Istanbul). Izel and Doret were our hosts (mostly interacted with Izel). They provided lots of great information and recommendations. I had already had great experiences renting apartments in other cities before this trip to Istanbul, and yet was still impressed with the small details they had thought of which made our stay really easy so we could concentrate on enjoying the city. There is some construction going on nearby, so you might want to bring earplugs until that is finished, but overall a wonderful, spacious space with great light in a good location (the stairwell is unglamorous, but just wait, the apartment is wonderful!), with excellent hosts. Highly recommended!
