Salih's flat is cozy and comfortable, and actually occupies an entire floor of the building. Living room faces the street and has large couch in front of a TV, and a working area. Internet is really fast. Bedroom has a balcony on a backyard and a comfortable bed.
There's everything you could need for your stay: shower and hygiene products, spacious washing machine and dishwasher, towels, bedsheets, slippers.
Salih is a wonderful host, always ready to help, knows everything about the city, very polite and responsive. I'm very happy with my stay and am definitely staying at Salih's house again when visiting Istanbul.
