The flat is lovely with interested decoration. Murat and Alper picked us up when we arrived. They are quite friendly and fast to answer our questions.
We visited Alper's restaurant with traditional Turkish breakfast near the flat. Then way down to the subway at Kabatas station in 10min, to connect bus, subway,ferry and gorgeous sea view ( Recommend this route without climbing a slope).
From Taksim station is the way we go back to the flat 5-10 min(no uphill as well), and we found lots restaurants and groceries.
