We choosed the Amir Kabir because of our late arrival and the good price in our guide book. When we checked in, it turned out, that the price had increased 10 times compared with the travel book. We where shocked. Usally we seen prices increased by 50-300%. But not 10x.
And what we got for that price was low hostel standard: Tiny room, shared bathroom, no towels. We moved the next day to a really nice hotel, with clean rooms, towels and own bathroom and paid only 100K Rials more (about $3).
