My stay at Deniz’s place was very pleasant. The photos are a good representation of how the apartment looks like. The apartment itself is situated in a very good location - close to Moda and Kadikoy’s bull statue bur also in a quiet street. It was cleaned everyday and we were provided with new pair of towels, slippers etc. on a daily basis.
Deniz was very friendly and responsive - one night the AC in apartment started leaking and he got it fixed the next day.
Overall, I would recommend this place and will definitely consider staying here again if I visit Istanbul.
