Mr. David is definitely a friendly and easygoing person. He showed me the way to the Manchester Airport while he was taking his dog for a walk. It definitely proved to be an useful insight. The bed might be a bit small if you're about 1.8 m tall (you'll have to squeeze in a bit, but it's manageable and comfortable).
However, I did find one thing that I didn't particularly enjoy: some leftovers of toilet paper inside the toilet that looked gross.
Also, you might ask Mr. David. how to turn the blinders on and how to turn off the radiator so the room doesn't get too hot. That's another detail he forgot to mention.
Other than those minor and slight inconveniences, everything about my one night stay was great. I will consider this accomodation for commuting to the airport again.
