I received a photo from a dear old Turkish lady from Bursa who I met on holiday in Fethiye last year with this written on the back:

Sevgili Bob,

Nermin teyzenin istanbul hatırası inşallah bu yaz gene buluşuruz Temmuzda Fethiyedeyiz Hayırlı günler Bursaya da bekleriz

Nermin

My guess would be something like:

Dear Bob,

Auntie Nermin´s instanbul souvenir. I hope we meet again this summer. We will be in Fethiye in July. Also waiting for happy days in Bursa (?) 

Nermin

Can someone give me a proper translation please.

You guessed it correct. And here is the part you confused:

"Also waiting for happy days in Bursa (?)" should be "Good days, we´ll wait you for Bursa too"

çok sağ olun Faruk!
