I really liked Tulai’s flat. It was very clean, has enough space for 1-2 people, all necessary things for cooking. It’s about 10-15 minutes walking from 4. Levent metro station (great when coming from Sabiha Gökçen airport with the E-3 bus); it’s partly hilly but definitely manageable.
I really liked the east check in, rooftop terrace and gym.
I can highly recommend staying here.
