Louis' place is exactly as described - perfect to sleep at while you go out and enjoy the city. The top bunk is a firm mattress and the bottom is cushier, so we were able to pick our sleeping locations based on preference (it was nice both weren't firm!)
Louis was clearly an Airbnb pro and gave us all of the information we needed to feel comfortable with our stay (instructions/addresses/etc.) Also, it seems that he is rented out the majority of the time, so he doesn't stop his life/activities because you are there.
Sam the cat was a crack-up and we enjoyed his presence.
The main drawback for us was the distance to the public parking lot - if you are planning on driving in and using your car, just know that you'll have a 10 minute walk or so to get back to it any time you need it. Just hadn't planned for that, so we left the car and Lyfted everywhere we needed to go. =] I didn't see that detail in any previous reviews.
Again, I really enjoyed our stay and would stay here again. It felt like a spontaneous adventure. If you're with (or are!) someone who is super structured and prefers a hotel-like experience, I wouldn't recommend it, because I think you do need a little bit of a go with the flow attitude to appreciate the experience. But if you are looking for a safe, clean, inexpensive place to stay that's a little outside of the norm, go for it. <3
