The accommodation is very close to popular sights like the blue mosque, just a five minute walk. Next to the building is a little shop with fruits and vegetables and water. There are some more other little grocerys around. The metro is also very close. Ugur offered access to another balcony with a great view to the ocean. His wife came and granted me access.
When I was there they demolished the building next door and it was very loud during the day.
The place is good for a short stay in Istanbul, especially when your doing your tourist things the day.
