We are in Beyoğlu, which is Istanbul`s center for entertainment, nightlife, culture, and shopping.
Beyoglu is live almost 24 hours, which means you can go out relatively safely even at nights. You will have the widest choice of cafes, restaurants, various shops, bookstores mostly lined alongside İstiklal Street at your service even at very late hours.
There are three museums nearby that might be interesting to see. Pera Museum, İstanbul Modern Museum are in the same street as Hotel Troya, Galata Dervish house is on Istiklal Street.
Taksim Square which is like the transportation hub of Istanbul, is only 950 meters.
Major tourist attractions in Sultanahmet area, such as Blue Mosque, Hagia Sophia, Topkapı Palace, and Grand Bazaar are at approximately four kilometers distance, and the best way to get there is taking the T1 tram line from Karaköy Station, since Sultanahmet area is mostly closed to traffic.
