this studio is surprisingly cozy for its price. it is pleasure to be there. but the good price is more than reasonable because of some disadvantages:
1) many things didn't work: fridge, TV, kettler.
staff replied quickly and immediately changed the kettler, brought a cooking board, tried to fix TV. (about the fridge we noticed just before checking out)
2) communication. the staff member was annoyed on check in. and TV situation was unpleasant. they just thought that if they did "everything they could" we must be happy and don't deserve apologies. but we needed TV for new year night (Russian tradition), not their efforts.
when checking out, we suggested to compensate it by transfering us to Taksim square (max 20 lira on taxi). we would accept any answer, but not blaming us for them missing the next night for this studio because of our check out 45 min later (time suggested by the owner and calculated exactly to make cleaning before the check in time!) That was even funny.
so, this is a really nice place to stay if you are okay about not making friends with the hosts + you should be ready to unexpected situations.
