We stayed in this apartment for a week and found it very close to Taksim square and other amenities like groceries, coffee shops and Starbucks. It was easy to do a lot of things by foot. The entire locality is settled on hills and require steep walks towards the Taksim Square and Istiklal Caddesi
Mustafa was helpful, supportive and resolved initial concerns on the same day. The apartment is simple, clean and equipped with as described amenities like towels, toilet paper , shampoo and equipped kitchen. There is a surpised little balcony at the back which was not the in the discription but we liked it. It was a good small area for tea/coffee and smoke.
We needed a bit of learning to operate the keys into building entrance and apartment door locks surely it can be improved. Building entrance illumination is not great (instead of a manual-timer-switch it could have been an auto-timer-lightning for good experience).
Overall our stay was good and host was welcoming.
