Centrally located in Besiktas with all nice bars/restaurants next door. As mentioned by others before very loud also during the night.
If you are on a bachelor party and your idea is anyways not have too much sleep, you can consider to stay here. If you are travelling with your partner this is rather a disgusting place with Urin in the entrance floor and mould in the bathroom…besides, aircons are very old and not really working/cooling.
Make up you own choice
