We spent three days and nights in Erdem's apartment, and we had a very good time.
The apartment is perfectly situated near Galata Tower, but yet on a quiet side street.
Within short walking distance, there are countless shops, cafes, and restaurants for every taste.
Nearby is a metro station and within 15 minutes walk there are the major ferry hubs to other neighborhoods.
We found the apartment very well equipped and perfectly clean, comfortable and beautifully designed.
The host is very friendly and helpful, and always responsive.
This was our first visit to Istanbul, and we will definitely come again.
