The house is about a 5-7 min drive from the Istanbul airport. Although the price for a taxi is not strictly fixed, you could pay between 100 lira and 10 euros (more than 200 lire). I tried to use Bitaksi app, but I cannot pay with my Revolut card for my trip.
Ahmet is very kind and friendly. I felt the atmosphere of a Turkish family there. The host serves breakfast and dinner on request.
The house is very new and the interior works are not completely finished so far (hopefully, it will be finished before the summer season), but this did not really disturb me. If you would walk around, you turn out to be in a Turkish village with chickens, sheep, dogs...
Overall, it is a good place to stay for 1-2 nights between flights.
