We visited a house

My lease will be over this August and I need to find another place to rent. I wanted to rent a room in a house instead of contracting for another apartment. The room is cheaper, and it is not required to have a long lasting contract for it.

We went to see a room that I found its advertisement in the Criagslist website yesterday. It was very close to the university, and the neighborhood was better than my current living place. The owner was an American man around 35 yo. He showed me the room. There were two issues with the room. It doesn't have a private bathroom, and the house was dirty. They walk with their shoes in the house. I don't like to live in a place that people walk around with their shoes. 

This was very disappointing. I always wanted to try living with an American person in their house to have a closer understanding of their living style. But I don't like to live in a dirty place. In addition to that, I want to say my prayer everyday. How can I do it in a dirty place like that. I don't say that his house was dirty, but I didn't like the fact that they walk around with shoes.
