I have 2 large private room with a large balcony has Bosphorus view.
The flat is in the center of Istanbul. Usküdar is the best location in the asian part if you want to stay close all famous places you would like to visit. Üsküdar has became a transportation center. You can go where ever you want to go so easy and fast with 4 different option from Üsküdar. Ferries, Busses, Dolmus, Marmaray.
I'm an architecture student at Mimar Sinan Fine Arts Univercity. I'm living in center of Üsküdar. I'm using little ships to cross the Bosphorus to get my school. It means everyday morning seeing birds while flying after your ship and smelling the Bosphorus and that's making my first smile of a day :)
Üsküdar is a quite and peaceful place. It has many historical mosques and houses. Center of area have everything you need for example bazaar, shops, markets, tool shops and old furniture salers so on.. By the way, when I'm coming back to House, I use the way inside of the Valide Sultan Mosque to hear some silent from city noise. You'll see sweet cat's everywhere :)
