The owner was kind, described how to get the house and sent the point on the map. He waited us inside when we arrive and provided big bottle of water in cooler.
The view is fantastic, you can see all city center and the bay.
There are a lot of dishes in the kitchen, you can find everything what you need.
We visited Istanbul in January, and it was cold inside in spite of using electric heaters, especially in bathroom.
The flat is on the top floor and there is no elevator. It can be difficult for people with health problems to use 5 levels of stairs every day.
The flat needs the renovation, looks not such new as on the pictures.
Beds are uncomfortable and too soft.
The boiler for the hot water is enough for 5 minutes, after using it other guests need to wait at least 30 minutes to take a shower for the other 5 minutes.
Internet connection is slow.
