We were at Asli & Ali's apartment for five days with four people and can recommend the apartment as well as location to any visitor of Istanbul. It is located in a very nice neighbourhood with great cafes just outside, perfect to enjoy a tea in the morning and grab some Simits for breakfast. The city easily reachable on foot, but also public transportation (T1) can be used to reach points that are a bit further away. A Taxi is driving by every 20 seconds, so this is no problem either. Ali gave us a good introduction and tips for cafes, bars and restaurants. Thumbs up!
