We enjoyed our stay at Nur's house. Everything was very positive: our communication (instant and very friendly), location of the place (a wonderful Bosphorus view), equipment of the house, organization of our arrival and departure.
We have chosen this option because of its proximity to the starting point of the Bosphorus cross-continental swiming race, so I would highly recommend it to interested athletes, especially if they are coming with families, like we did.
The house has spiral stairs, so please take care if you have children.
