We had a wonderful time at Berk's place. He provided all the necessary information beforehand. His assistant Byram was there to welcome us and also helped us with luggage and finding a place to eat Berk was very responsive about our good place to shop, taxis, finding metro and flights. The place is located very close to Galata port. 5 mins of walking. overall we are very with his service and place.Will definitely recommend to others
