We really enjoyed staying at Mia's place. The flat was clean, check in was well organised and Mia was very good with communication throughout our stay. Plants, decoration, piano and home entertainment made our stay very comfortable.
The location is perfect for several outings a day, and being able to walk to ferry stations is great bonus. We had a very enjoyable trip to Dolmabahce Palace from the flat just taking one ferry to Besiktas. Having local shops for fresh produce just outside along with a good fridge given us a opportunity to enjoy our breakfasts at home.
I'd highly recommend Mia's place if you are visiting Istanbul.
