Volkan was a great host, very responsive and he let me leave a bag there for two weeks.
the studio was nice, equipped with a hotpot and small fridge, good AC, strong wifi and even a small terrace.
the day I arrived i don't think the cleaner had finished cleaning as there was still trash from a prior guest inside and no towel or top sheet, but Volkan had these dropped off and I was happy with the unit in general. the only complaint with unit 103 is that it's directly behind a little reception area where people would talk loudly and smoke. i had to block the gap under the door and even then sometimes cigarette smoke came into the studio. sometimes I could open the terrace door and air it out but smoke often came from that direction too. cigarette smoke seemed to be unavoidable and was my biggest concern in Istanbul.
easy check-in and out, room as described. bed comfy and shower was good and hot. it's fine for a short stay if one can manage the cigarette smoke. the upstairs rooms may not get as much smoke smell.
