I recommend the small economy room if you are travelling alone, want to save money and are not sensitive to noise, or if you don't mind using earplugs. The room faces the reception area, so you can sometimes hear people passing by and guests arriving.
This is a family-run hotel with clean and well-maintained rooms. Housekeeping was done daily, including fresh towels every day. The air conditioning worked very well, and the staff were welcoming, friendly, and helpful.
The location is excellent, just a short walk from Hagia Sophia and the Blue Mosque. The small bakery next door is also very convenient for breakfast or a quick snack.
The only downside was the laundry service, which was quite expensive. I recommend asking for the price beforehand to avoid surprises
