I had a beautiful vacation with my son in Istanbul. We stayed only a few days, but we visited all the nice places around the new and the old town, and also the Asian side.
Osman was our host. He was very kind and polite person. He gave us the recommendations about where to go, and he kept good contact with us before and during our stay. He even borrowed us the bus card.
The apartment was clean, and had easy access to many attractions.
Although we had mostly aprox 15 minutes walking distances to the main transports... it was a hard up and downs streets to walk.
For the guests with heavy luggages, the apartment is located on the 4th floor.
We were a bit disappointed with the roof terrace. The view was very beautiful, but during our visit it was a bit dirty and even with broken chair.
But the experience in general was positive, and I do recommend Osman apartment.
