We stayed at Kerim's place for almost a month, and I cannot recommend this place more! The location is super prime, and a few steps away from the metro stop. The apartment itself is very modern and clean. We really enjoyed our stay at Kerim's place, and especially enjoyed the fast response and all the help that we received from the building's support team, Hatice & Mehmet.
PS: You also have a bonus super cute cat that stays in the lobby of the building! :)
