I opened an account with Finan Bank and the lady who deals with the accounts (English speaking) is Ayse, she was recommended to us. We turned up 5 weeks after originally opening our account in order to collect our ATM cards and she smiled, said hello and knew who we were by name - amazing!
Ayse is always busy and you will probably need to wait whne you get there, but I class that as being a sign of good service. You can always chat to other buyers while sitting there. We had intended to use Garanti but when we went to the bank the lady did not speak English (our problem not hers) and they also required a tax number and Finan did not. Heidi uses Finan and sent us their way and we do not regret it.
Ayse did all the form filling for us, explained everything very patiently and is a lovely girl - I hope you pay her well Finan Bank - she is worth her weight in gold.
