Ali was there and waiting for us when we arrived and he was an obliging and considerate host. He even got up early morning - we left at the crack of dawn - to see us off.
The apartment is well-situated, especially if you're looking to stay in Sultanahmet, since it's within walking distance to all the sites (about a 10-minute walk) but still removed from the touristy hustle and bustle (which can get crazy this time of year).
The neighborhood is full of restaurants, dessert shops (even a 24-hour one!) and lovely cats :)
The apartment had everything we needed and is well-organized, clean, and cozy. The beds - even the sofa bed - were comfortable. There's a small kitchen and a fridge, and 'though the settings are a bit too small to cook in, it's more than enough for quick snacks and beverages - there's even a Turkish coffee maker provided. Plus, there are more than enough restaurants around.
The only drawback to our stay was that the ceiling was thin and we could hear everything that was said/done upstairs, which might not be a problem if there are no guests staying upstairs, but could be a bit rough when there are (we eventually had to go upstairs and ask the guests to keep it down after midnight).
Overall, the host is always on-site, the location is good, and the apartment clean and cozy. It was a good stay :)
