Location was outstanding, right in the middle of the charming and lively neighborhood of Besiktas. Very close to everything you need to get around Istanbul: public transportation to take you to the main tourist sites, harbor where you can take the ferry to go to the Asian side (Kadikoy) or book a cruise on the Bosphorus and easy connection to the airport with the IST-5 shuttle (cost 16 Turkish lira/person.
The apartment was super clean, not super spacious but easily accommodates two on a city break.
Lastly, Adroniki is an amazing host and the checking/checkout process is very efficient. Highly recommend!
