Joe and Alex are very friendly and very helpful. They helped me to navigate my way around the city and Joe was always accessible to help if I had a question or problem. He really cares about people's experience of the city and their stay. I had a great time at their home.
As for the house and the room, they're nice. There are two bathrooms, which is great, and there were two closets in the room I slept in (which allows each person to have a space for his/her stuff). The description on the website is very accurate.
