Sahin was an excellent host)
He tried his best to provide his guests with anything they might possibly need, was at easy reach all the time, 24/7, gave local tips, helped with check in (though it was late in the evening) and in general gave the impression of very polite, thoughtful and pleasant man.
The Appartement itself was clean, had everything you might need for your stay like iron, TV set, kettle, cooker, and even wash machine.
The apartment is good and safe located. And apartments style (old building with with winding stairs, tiny but cute balcony, art work pieces and decorations all over the place) is worth separate attention. They really made you feel the vibe.
The only minus was noise at night from outside but that was bearable.
I’d totally recommend this place and this host to anyone visiting Istanbul)
