Value is a funny thing. It varies from person to person so comment that I loved it there may not do justice.
I was looking for a place with a Bosphorus view and quick access to all the happening places in Istanbul. The host was very responsive and helpful. The apartment inside is following a minimalistic yet adequate setting.
There are two things that one needs to consider with older people or kids that it has no elevator and top floor. I have 2 younger kids and it is not a problem. And my mom who joined us at the last minute with two bad knees still could go up.
The second one is that if you have a car then no parking and even no way to park in front of the door but again no problem for us.
Overall, once of my favorite places to stay in past 40 years that I have traveled around the world.
