I was a little bit disappointed with this stay. I booked two room types, one is a standard room and the other is a twin room, which are in different buildings, but because the structure of the house should be wooden and the windows are not well sealed or double laies, the 2 rooms windows face the railway tracks. It was very very noisy every day especially at night because the trains passed by almost every 5 minutes (and rang the bells). During the day, we were very busy traveling around, so I didn't report this to the front desk. If you are a very sensitive sleeper, please don't consider this hotel or make sure that the windows don't face the railway tracks. Although, this is indeed unavoidable, after all, its location is excellent, right next to the Hagia Sophia Mosque, which can save a lot of time, and its house foundation is also very old, so I can fully understand.
The hotel's Turkish breakfast is worth trying, with a variety of varieties and good taste. (I have lived in Turkey for more than 1 year), the service staff is very friendly, and the hotel facilities are actually well maintained. Their historical jacuzzi pool is highly recommended, my children had a lot of fun, 40 minutes is about 60-70 euros, this is an additional payment, if you are a family with children, it is recommended because it is private for 40 minutes.
