Mama Ghodsi's house is very very nice and cheap place for staying in Tehran. I was in Tehran for 2 months for internship and I chose her place for staying. She is very kind and funny woman and her place also suitable for staying during traveling in Iran or staying for a while if you have to spend some time in Iran. You will learn Iranian nice culture from her also you can try Iranian food that she will always cook for guests. You will impress her place like me! I promise.
