Tansel was prompt and helpful in all his email and phone interactions.
Two of us originally booked with Tansel. Later, we wrote and asked to bring a third person. The 2nd room wasn't ready when we arrived. But he worked to get it ready while we were out for supper and seeing the town.
We had arrived earlier than expected. His mother welcomed us in the garden out back which is being worked on and will be lovely when done. It overlooks the old wall of the city out to the Marmara.
The location is unbeatable - just a short walk up the hill behind the Blue Mosque. Tansel provided helpful history and site suggestions. He provided a mobile for use in contacting him or the cab company.
He called our cabs the morning we left because they don't speak English. He and his mother both speak English very well.
Overall, it was a great place for our short stay (1.5 days). I would definitely recommend booking with Tansel.
