I stayed at Hakan`s place for a second time and can only reiterate my first impressions! Haken is very hospitable and can assist you with his very detailed knowledge of the neighborhood. The apartment is very clean, everything you will need is available from washing machine to dryer, and you are located in the heart of Istanbul`s very popular neighborhood of Beşiktaş, which is full of nice cafés, restaurants, and pubs. Transport is also one of the big pluses: Central bus lines are running just around the corner (where also buses from Istanbul Airport arrive) and ferries to the Asian side are only a ten minutes walk away. I will definitely stay for a third time when in Istanbul again. Thank you!
