Me and my husband spent 4 nights at Senatus Hotel in October 2012. The hotel is a walk away from all the must sees of Istanbul. The rooms are very clean and the service is splendid. The hotel managers are extremely friendly and more than willing to help. We had initially booked an economy room but due a small leak in the bathroom (which got repaired in few hours) , they upgraded us to their best room. And what a room it was..Huge and super cozy !!! We did a trip to Cappadocia for 2 days and they allowed us to leave our bigger bags in the hotel.The breakfast at the restaurant could be a little better. Would definitely stay there if i go to Istanbul again..Thanks for a wonderful experience!!!
