Nida and her husband made us feel very welcome from the very beginning. Unfortunately we did not get to meet Nida during our stay but Nida's husband was very helpful in organizing taxis for us, giving useful tips where to go and what places to visit etc. Special thanks for the assistance with our hospital visit as my friend injured her foot on the first day.
The listing is exactly as desribed: clean, nice, comfortable, with all amenities required. There are food shops just around the corner and a very nice little bakery. The food market on Sundays was very convenient which starts just around the corner. Istiklal street just 100 meters away and Taksim is not far as well which offers plenty of nice restaurants and bars to go to. The location is very good and safe.
I would stay there again when visiting Istanbul again.
