Pelin welcomed us with so many nice indications on nice places to go, and her flat is really well situated, not far from tram (10 min), from istiklal busy street (10-15min), but in a far less noisy environment.
The immediate area is also really nice, mixing traditional shops (you have to try the little yogurt shop Özkonak lokantasi on the other side of the street, they're so friendly and so good!) and very nice restaurants, some classic, some more trendy... that really represented to me the spirit of Istanbul.
Some may consider at first sight Istanbul is a mess, I found it's this place is a wonderful example that people of different cultures, generations, religions & origins can live respectfully together, not in seperate and closed communities.

The flat by itself is really nice, conform to the nice pictures, and we enjoyed it a lot after a good day of walk (& turkish delight tasting...) in the city !
Thanks a lot Pelin for your warm welcome and your fine advice on places&restaurants, be sure I'll tell about your place to my friends & colleagues :)
