Amazing apartment in a great location in the middle of Kadikoy, and the terrace is the cherry on top - we caught a few beautiful sunsets from there. Its also just 10 min walk to the ferry station for trips to the European side or the islands.
Communication with Alper was great and seamless the whole time and we loved all his recommendations, so definitely check those out.
Would 100% stay here again on a return trip to Istanbul.
There's an elevator but an extra set of steps to the apartment so not fully accessible for wheelchair users.
