Pros: Location, view, shower, air con
Cons: WiFi barely works or not at all. Electric goes out alot making refrigerator unusable. He can turn electric back on if you message him. Hot water goes out but you can message him to turn on. Kitchen poorly stocked, things broken and dirty. Linen is very low budget scratchy, has holes, thread bare and misshapen. Local hostels have better linen. Room was dirty when I arrived, no cleaning matterials provided and have to give consent to clean a bunch or times in the same day. Security wasn't comforting. He knows when you leave/return and a bit too attentive in that regard. I found the keys to the whole hotel left on the banister outside of my room very early one morning (500am). He told me not to bother using the locks on my door because he was watching out. Alot of communication required just to use the space. I prefer a smooth stay and generally have long stays without contacting the host. This stay required daily contact and if I asked for everything in the listing, I would have been down right annoying, so I made the most of it.
I love Istanbul so the trip wasn't wasted but I wouldn't recommend this accommodation.
