We had a great stay at Akins place!
He always answered super quickly if we had a question, helped us finding a safe spot for our bicycles and the closest supermarkets.
The flat itself looks a lot nicer than it does the pictures and is very comfortable. The kitchen is equipped with everything you could possibly need and there is lots of space for preparation.
The only thing that could be added to the flat would be a table and chairs, as it was a bit difficult to eat while sitting on the sofa.
The price-performance ratio was just perfect and we would definitively book the flat again for our next stay in Istanbul.
