I had such a wonderful time visiting Istanbul, and staying in Sina's apartment was a special part of my visit!
The communication was always very prompt and informative, and the staff at the Rappel Cafe were incredibly nice and helpful. I was thoughtfully provided a "welcome package" featuring an assortment of good information. Also, the location was great... close (walking distance even) to several sites and areas like Galata and Taksim/Istiklal Street. The neighborhood (Cihangir) has a nice bohemian vibe with quaint streets, shops, and restaurants. I was constantly told by locals who live in other parts of the city that the neighborhood is considered a prime area.
The apartment itself was immaculate and the impressive interior design resembles attractive aesthetics like those featured in Elle Decor or Architectural Digest. To top it off, the large windows provide great sunlight, and an even greater vista that shows off the neighborhood building landscape, and the Bosphorus Bridge in the distance. A lovely sight to welcome each day.
I deeply enjoyed my stay there and would visit again!
