Despite that my very short stay at Fatos', I can certainly feel her hospitality and her considerations of the guest's needs. Everything is very clean and in good form.
Regarding location, it's certainly ideal for those in transit in Istanbul (about 15-min drive from Istanbul Airport), but also for longer-term stays if a quiet and spacious living space you're looking for. Fatos also offered airport transfer, with a fee, which is handy as it's almost the same as what you'd pay for a taxi. From Fatos' to Istanbul, it'll take about 30 mins by car, but you'd need to ask the host for more logistical details.
More importantly, Fatos is such an interesting character who's more than ready to share her stories as much as she enjoys listening to yours. I'd highly recommend Fatos' place for the above reasons.
