We stayed for about a week at Banu's place. The location was super convenient, 12 minute walk from Taksim square. The apartment is located in the basement, so there was only one set of stairs down in the building.
Overall, the photos matched the apartment, it is beautifully designed. There is a washing machine to do laundry which was very convenient. There is heating in the apt and also there is a net on all the windows, so we opened them without fear of getting the insects in. We also felt very safe at the location.
There was a smell each time we came back to the apartment, but I would say that it is due to humidity, when we were at the apartment, it did not bother us.
The only piece which I thought could be added is just some drawers, but it was not an issue for us, we loved the place. And sometimes the noize from the street or upstairs neighbours was a little loud.
Other than that, we loved the location and we thank Banu for being such a responsive and kind host to us.
