The apartment is in a block (I think all of the apartments managed by Celal) in a fantastic location – 10 mins walk to Sultanahmet, less than 5 mins walk to the huge selection of restaurants in Kumkapi and the same distance to supermarkets/grocery stores. It’s on a quiet road which felt safe at night and the bedrooms face the back so there is no road noise.
Celal is an amazing host – super friendly and helpful. He organised our airport transfers, was there waiting for us at the apartment even though the incoming flight was delayed > 1 hour, with halva and Turkish Delight! He sent us a list of all tourist sights and places to eat and messaged us every day to check if all ok. He was also there at the end with a leaving gift.
Unfortunately we had to stay in the apartment above the one we had booked on the 1st of our 5 nights. Although the layout was similar, it was not in as good condition as the one we booked. Celal was very apologetic and was able to move us to our booked apartment the next day.
The booked apartment itself was spacious enough for a family of 4 and had most of what we needed. Our only suggestions would be that (1) it needs a bit of maintenance and refreshing (eg the drawers in both bedrooms were broken), (2) the kitchen could be better equipped (we ate out most of the time but would not have been able to cook anything substantial with the equipment there) and (3) that the apartment could have been cleaned more thoroughly before we arrived (eg there was rubbish under the beds, some of the glasses in the kitchen were dirty etc)
