we like the central location of this place in sultanahmet. Close to all major sights and few grocery stores near by as well relative inexpensive restaurants.
It is located on the 3rd floor (2 flights of stairs), so will requires lots lifting to get your big luggage up and down. The build is old, but the room has all the furnishing, appliances, and kitchen wares for guests to cook/eat. A microwave oven is a bonus.
We are a party of five, 4 adults and 1 toddler, it is a bit tight since we needed playpen/high chair, the owner provided these, which is very nice.
Room has nice wall decoration - paintings.
Couple things that would make it even nicer are:
The dinning table light could be brighter and warmer color (say yellow color LED of 100w equivalent), we felt it is too dark and gloomy there while sitting to eat. The hallway/kitchen lights are also white, but didn't bother us as much.
more outlets at convenient places to charge electronic devices. there just not enough outlets for modern multiple devices crowd :)
