This is an excellent apartment in a vibrant location only minutes from Galata Tower, a popular attraction for both locals and tourists. All the main tourist sites in Sultanahmet can be reached in minutes by taxi (about €4/5). It also provided easy access through narrow cobbled streets to Karakoy where frequent ferry services operate to take you to the Asian side and many other destinations. There are lots of good restaurants within easy walking distance and the host Izel will be happy to make good recommendations !
All communications with Izel prior to traveling were handled promptly and efficiently. He provided pinpoint directions and travel advice from the airport to the apartment and gave us his mobile number so we could contact him by WhatsApp with any questions/concerns during our stay and arranged to meet us again on departure to ensure that we got a taxi at a busy time of morning to take us to the airport. All of this provided significant peace of mind for first time visitors to Istanbul, a large and complex city.
