cellar door

In the bracing world of 'phonaesthetics' (a word that only exists in the bracing world of 'phonaesthetics') the phrase 'cellar door' is considered the most generally appealing in the English language.  The research that went into this was categorically the best use of money ever.  It's probably also the most useless piece of information that I (and now you) know.

Of course, this hasn't stopped people from turning it into a name (Selador or Sellador).  This means that Hermit Hortense now has a definite competitor on my list of beautiful names.

Unfortunately, 'cellar door' doesn't sound nearly as well in Macedonian.  I'm also betting it's not as alluring when Stephen Hawking says it either.
