Purun's place was fantastic! I stayed there with my boyfriend for about 5 days. Within 24 hours we felt comfortable navigating the bustling neighborhood (though the apartment itself is on a remarkably quiet street) and taught ourselves the easy walking route down to the ferry on the Bosphorus. There are tons of little markets, shops, cafes, and pide/börek places very nearby. The apartment was clean, bright, nicely decorated just like in the photos, and everything in working order -- though it was a bit hard to warm the apartment up, as we were visiting in February and it is a basement unit. Unfortunately, we didn't get to meet Purun and her husband in person, but Purun was quick to reply to all my questions via e-mail. She also gave us her neighbor's phone number (he met us at check-in) which put our minds at ease. We would happily stay there again, and we'd happily host Purun and her husband if they ever find themselves in the Washington DC area.
