Mersin was really helpful throughout my visit, and gave me tips about what to do in Istanbul. The flat was clean, spacious and had high standard. It had everything you need and more, for example a washing machine. The neighbourhood was really authentic and it had small shops and cafés. The flat was located about 100 metres from Istiklal street (main shopping street) and about 200 metres from the Galata tower with its cosy cafés and restaurants. I would definitely recommend Mersins flat as an accomodation for its high standard, cleaniness and location.
