Spacious and clean apartment. Has a terrace with a great Bosphorus view. Location is also great, which is close to Galata Tower, Tarlabaşı boulevard (has many shopping and eating venues), Taksim square, T1 tram station (fast trams that reach Sultanahmet, Kabataş and Dolmabahçe Palace).
Eyp is a great host. Always ready to help or advise.
I highly recommend the apartment and the host.
