I had a very short, one night stay at Sinem and Olga's place (I'm a New Yorker, but lent my apartment out to visiting relatives for a night), but it was a really enjoyable experience. I only saw Sinem midday to pick-up spare keys to her place, but she was very easy to communicate with and and was very pleasant. The apartment was small, but very cool and cozy and you can't beat the location. It's in the heart of the LES, with tons of great restaurant, nightlife and shopping options within a few blocks. And while the bedroom was small, it was more then enough for me to store my stuff while I was out and about during the day.

Overall, a really positive experience, I would consider staying at Sinem's again for sure.
