Hi! This is what I found on the web --> Istanbul‘s Special-Class or Special category hotels offer character, specifically Ottoman character. Some were built during the Ottoman Empire, others have been restored to the character of that era, still others strive for an Ottoman ambience. Recognizing that some unique hotels did not fit its standard star classification system, Turkey’s Ministry of Culture and Tourism created ‘S’ (Special) Class to designate hotels and inns that may not meet all the technical requirements for a certain star rating, such as number of guest rooms or restaurant seats, but that had other advantages, such as character, historical interest, and/or charm. Special Class hotels are smaller than the standard 4- and 5-star luxury hotels, with fewer staff whom you’ll get to know more easily. Each has special charms or advantages. Most are as comfortable as any modern hotel rating three or four stars. Many are located in the most convenient hotel districts. And I would attest to the charm - Levni Hotel is not that big but the hotel staff are so nice and they can remember your names and call you by name. They also offer personalized services - the concierge in Levni offered to order food for us on our first day because we arrived late already and the hotel restaurant was already closed. He used his personal phone's app to order food for us and even brought so much bottled water when he brought the food to our room. He even found a great laundromat for us.

I was a guest. Best contacting the hotel directly
