We only stayed here overnight but we were very happy with everything during our stay. We arrived late and was welcomed with tea on arrival and check in was pleasant and easy, with advice on the local area etc.
The room was perfect, exactly as the pictures advertised. Location was very central to all the tourist spots. The grand bazaar was a short walk away, as well as the blue mosque and others.
I would recommend a stay here and would certainly stay if I was to re visit Istanbul again. Thanks :)
