Efecan’s place is beautiful, clean, well equipped, and incredibly well-located to explore Kadikoy and the Asian side, in general. It’s a fifteen-ish minute walk to the ferry station from where you can catch a bus, a dolmus, or take the ferry to the European side. Efecan is an awesome host, too! He is super responsive and available to answer questions or help you out during your stay. Highly recommend staying here if you visit Kadikoy!
