I stayed at the Inera for one week in April, 2017. The hotel is new, very clean, and modern. The staff are professional, courteous, friendly, and helpful. I and my Turkish-born wife are frequent visitors to Istanbul. This small boutique hotel was a welcome surprise. I hardly know where to begin. The stone-tiled bathroom had a heated floor(!); I loved it. The shower stall was spacious and had an over-sized, total-shower, shower head as well as the usual shower wand. The breakfast buffet was generous and varied and offered a delicious range of Turkish breakfast choices. The bed was large and comfortable and had high-quality, feel-good, cotton sheets.
The Inera is situated in the heart of Pendik center and within an easy walk to the Pendik marina. The neighborhood offers a huge number of dining (breakfast, lunch, dinner, and afternoon cake and coffee) choices.
Special note* - Pendik is far-removed from the usual tourist spots Hagia Sophia, Topkapi, Grand Bazaar, etc.
So, if that's your plan, the Inera isn't the best choice. But, it's ideal for staying in Pendik, or, because of its immediate proximity to the marina, as an ideal jumping-off spot for day-tripping over to the Princes' Islands, or just for a good stay in an affordable, unpretentious, better-quality, modern, little hotel.
I would definitely choose it again (... and before staying at some other well-known, international hotel chains).
