this is someone's personal bookmark (I have closed hundreds of similar SITE or SUBJECT notes around the globus)
The latter may be realtor notes
People are (mis)using the poorly-named `notes' function for non-mapping infos.  The german OSM map refers to them as "Fehler" which I find a better term to encompass errors and missing data.  I've referred to these as bug-reports; on further reflection `Problems' seems a more appropriate term to discourage the general personal bookmarks like this, adverts, reviews, and whatnot unrelated to mapping.
Particularly since maps.me seems prone to dumping many things into notes that belong elsewhere.
Of course this is my own personal perspective, trying to keep a small handful of my own mapping notes visible amongst a deluge of irrelevant content, others may disagree
