I have stayed at a few places in Europe using Airbnb. I wasn’t that familiar with the term superhost, but I would refer to Dean & Meg as superlative hosts.
I contacted them with a very last minute booking. From what I can tell, both of them had to work all day but they still were able to take the time to get the place perfectly ready to go for me very quickly.
I was visiting and staying with my almost 17-year-old, very wobbly, senior dog. Even though she had a water bowl, she immediately opted for drinking out of the swimming pool. Of course she waited until I had walked away for a moment to do so. Almost as soon as I walked away I heard a very distant splash and ran back outside. Dean had also heard the splash and was already at the pool fishing my motionless dog out of his pool. She was totally fine, but his quick reflexes and thinking will never go unnoticed.
The next day, I actually went in the pool myself and it was wonderful. It was a pretty hot day out so it was perfect. The garden is gorgeous & a perfect setting to just relax.
In addition to being amazing hosts, I suspected these two are very good human beings.
I am sure that you will enjoy your stay there.
I certainly did!
