I have been staying at this hotel for more than 10 years, Again and Again, i definitely recommend it.
Despite that it is not luxurious, but when you stay there you feel like home. The staff are so kind and helpful, Rooms are very clean, and prices are so fair.
What distinguishes this hotel, his location which is almost 1 minute away from Sultanahmet square, where you can find all the sightseeings (Aya Sofia, Blue Mosque, TopCapi Palace,...). Also the tramway station is 2 minutes away.
Nearby restaurants and shops for all your needs.
I will be coming back anytime i visit Istanbul.
