bookstores in istanbul

hello!

ill be traveling to istanbul next year and im doing some research on bookstores before i go. im super interested in:

1) turkish linguistics and/or turkic languages 2) various language editions of the little prince (particularly minority language editions in turkey and the caucuses) 3) foreign language learning materials

does anyone know of any bookstores in istanbul that would be up my alley (doesn't have to have all 3 ofc)? i feel like when i try searching it myself, google always gives me english language bookstores, which is not what im interested in lol. im fine with books written in turkish/non-english languages, for the record!!

şimdiden teşekkür ederim :')
