We stayed for one night, and the overall experience was pretty smooth. The house is easy enough to reach by bus from the main stations, although it is a little far out from the city centre. Sadegh was a really nice host & gave us some useful tips to explore the city. He even made us tea & helped us book a taxi for the next morning when we had trouble with it. It's a good deal overall, but you should know that there are shared spaces, so you'll be sharing the kitchen & bathroom with the host.
