We were traveling as two friends and stayed at Mersins place for a few days only. Although we didn't meet him in person, the Check-in went very smoothly and he was responsive via mail at any time. The apartement was spacious and spotless. The flat is in a traditional neighbourhood in Istanbul with only short walking distance to Istiklal street. We were two women and felt safe at any time of the day and night.
We will stay again at Mersin's place.
