The apartment was sufficient for 4 people. Omer is an excellent host and very helpful and polite and helped us with our transfer to/from the airport. He responded promptly to our messages and we also had his phone number available for anything we needed. Although it is located in a somewhat narrow, secluded alley there were 2-3 hotels in the same alley, so there were people, therefore there was no reason to be afraid to walk around at night. Within walking distance is the Bridge and the tower of Galata, as well as the main street Istiklal. It is also close (on foot distance) to the T1 tram line (Karaköy station) which passes by key sights but also the Şişhane metro stop (M2) and Tünel (F2) ( Karaköy -Beyoğlu)
