I had a great stay at Asli's place. The apartment is very spacious and neat. It's completely ensuite and it's bigger and nicer than it looks in the profile pictures.
Moda is a fantastic neighborhood. It's very safe yet very lively and trendy and there are lots to do. It's not touristy as well which is great. Lots and lots of supermarkets, cafes, bakeries, dining options not far from the apartment. Some restaurants open overnight as well, even during weekdays.
Transportation wise, the mamaray railway station, the metrobus station, the metro station, the bus terminal and there are multiple ferry lines (both within Istanbul and within the country) all within walkable distance from the apartment. It's pretty convenient.
