Muge's flat was surprisingly big (even bigger than it seemed in photos), well-equipped, beatifully designed, very clean and comfortable for seven people. It's one minute walk from Istiklal Street, in the very center and next to public transport if needed.
The only sad thing that happened was a brief water shut-off in the flat due to the restoration of the Istiklal Street, so one morning we couldn't take shower, but the water came back very soon.
Muge though was wonderful host - responsive, helpful and polite. She set her friend up to meet us so we don't get lost and answered to every message very quick.
