Yusuf the owner was a great person, he directed me on how to reach the place, waiting on the front door, gave a very detailed map about Istanbul tourism place, and on top of all: allowed me to do early check-in and (very) late check-out :) The place was near to Grand Bazaar, only needs 4-5 mins walking and climbing. The road was sometimes uphill and could be tiring after a long-hard journey. The room was very clean though not so spacious. It was actually tiring to climb 4 levels to reach the room, but if you're young and energetic it wouldn't be a big problem. Definitely recommend Otantik Guest House for their cleanliness and great service. PS. They will take a photo of you while having breakfast, making you feel like some kind of celebrity who was asked for a photograph! :)
