The place is very clean and well equipped (central heating, reliable wifi, washing machine in the building, fridge and kettle etc). Unless you have issue with walking up hill (to get to the Beyazit tram station) the location is quite good - there are supermarket right across the street and other stores along the street. Some people mentioned noise from the street, i dont think it is much different from other places in SultanAhmet. Kadirga neighbourhood and the area around Kucuk Aya Sofia is beautiful and a short stroll away.
If there is any suggestion for improvement - the main door to the flat could be marked clearer (its the small door on the right in the alley infront of the Sok supermarket)
