We stayed at Fahrettin's place for 6 days, and it was great. Just as advertised, it is located very close to Istikal avenue, Galata tower and it is but a short walk to the Galata Bridge and Karaköy. The street is quiet in terms of pedestrian and vehicle traffic, though you will experience local colour such as the gas delivery jingle and of course the call to prayer first thing in the morning.

The apartment is clean and the pictures are accurate. The washing machine didn't work but I was probably just doing it wrong. When the internet stopped working Fahrettin made a great effort to come and fix it. He is a great host and was very relaxed about timing. He took us to a nearby place for our first meal and we chatted to the limits of the language barrier :) he also provided a guidebook. He was really welcoming and helpful. He was always contactable and responsive by both email and SMS/phone.

Regarding arriving at the apartment, this was no problem, we had printed off a map and Fahrettin provided directions, and the driver was happy to call Fahrettin to get exact details. There are a few local shops nearby all with very friendly shopkeepers who are eager to teach you a few words of Turkish!

I think it's great value and would heartily recommend it.
