Really fantastic place and stay. Located just enough off Istiklal to be quiet, this place is the perfect location as a home base for a small group when visiting Istanbul. We actually didn't meet Yasar, but got in really smoothly. We were checked up on a couple times to make sure everything was good. We had 6 people there and (while we wouldn't want to live like that for weeks) it was just fine for our 6-night stay. Check out the Syrian restaurant around the corner. Highly recommended.
