Such a welcoming host and a wonderful flat !! The beautiful, high-ceiled, historic building is basically located at the heart of the city. It is very close to the metro station, though almost everywhere is within walking distance. Besides Erol was very helpful about guidance. The flat was tidy and clean, decorated with comfortable and stylish furniture. I was also able to find every utility I needed in the kitchen. It was an amazing trip and I will definitely stay here on my next visit to Istanbul.
