This place is exactly what I wanted in Istanbul - I loved leaving the flat every day and emerging into the very heart of the bustling nightlife. Chilling out with the windows open, hearing the music and sounds of the city was a dream.
Necla and Pelin were great hosts, they were so incredibly accommodating, it was lovely to have friendly hosts in an unfamiliar city. Also, you should visit Necla's Deli/cafe!
Istanbul doesn't need any more written about it, it's charm are legendary, but if you're thinking about a trip here, do it!
