Very wonderful time at Basma's! A great introduction to Istanbul. She was responsive and helpful and made us feel at home. The neighborhood has some great food, and access to metro lines -- although we decided instead to walk everywhere. To Taksim it is about a 50 minute walk, and to ferries heading to Kadiköy about 30 minutes. This was ideal for us, but I'm sure it is easier by public transport!
All in all a great stay! :)
