This is a nice place in a quiet neighborhood next to Istiklal Caddesi. There are cafes around who play loud live music but, that didn't really bother us much once, we turned on the air con.
If you're planning to walk from Taksim Square, be prepared to walk a fair distance as it is easily more than a kilometre. Also, the location on Google maps isn't accurate. Best to search the street name or, ask your cab driver to take you there.
Very helpful hosts and a nice place.
