I don't recommend staying at Sam's. Before I got there, he had quite a few positive references, but I didn't enjoy my stay that much. It was dirty, he wasn't even there to take care of the cleaning. Bathroom and kitchen were (to my mind) super dirty and didn't get a clean up for a week, then I changed my booking and left earlier. I didn't even want to touch the sink in the bathroom or the fridge in the kitchen anymore. It was so dirty.
Sam seemed to be super nice when we first met, but after I changed my booking, he didn't respond my messages and ignored me in the house. I even apologised for leaving earlier (as I was staying with friends and then traveling to Halifax) and he pretend to be okay with it, but I felt like he treated me super rude and kicked out the morning I checked out. He seemed to have a huge problem with changing plans even though it was a flexible booking.
Also, there was a terrible smell in the fridge and it definitely needs clean from the outside, the inside and on top (there were onion peels and some other garbage lying on top for some reason).
There is also another guest staying and none of the doors can be locked. So, in case one of the residents forgets to close the door, your stuff can get stolen easily.
