We stayed at Ilhan's place for a week and had perfect experience. The apartment is located in a quiet family neighborhood but everything you need is within walking distance - shops, pharmacies, bakeries, restaurants, cafes.
The apartment is very close to both M1 metro lune and Metrobus stops, so you can easily and very quick any part of Istanbul.
The apartment is even better than the pictures - you have everything you need for a short or long stay - fully equipped kitchen so if you choose you can cook for yourself, internet with very good quality.
Last but not least, I would like to thank the host for being a very nice and responsive and helpful host. I hope to see you soon, Ilhan, as well as next time to meet your wife.
