Nice apartment. Can't say anything negative. Good place to stay for a few weeks. Host is always in touch. Location is 5 min walk from Taksim. Istanbul is a mountainous city so you have to climb up little bit, it can be a problem for old or weak people, but you can always go down to Kabatas and than take the funicular back to Taksim =) Also Kabatas is a good place to take ferry to Kadikoy and Adalar Islands.
