Halil is one of the best host. Location of apartment is very good.
Bigger curtain needed in room along with better lights.
Few extra things:
Do not buy sim card from airport it’s almost double prize.
Havaist 16 cost 52 lira per person and will take drop you in front of taksim point hotel.
From there it’s 10 mins walk to apartment.
Ask for istaklal street(it the grand bazar of taksim) when u reach there take the first left from almadina restaurant then take right turn into 2nd street and look for building no. 12.
Normal sim card of all network are minimum 350 lira. 20gb package.
Istanbul kurt doesn’t work on havaist bus I don’t know why.
