It's not a bad domain at all. Of course, the word maestro is intimately linked with music, and "music" and "love" go together very well indeed. Shakespeare's quote "If music be the food of love..." immediately springs to mind here, and the inter-play between these two subjects will surely be a formative part of the websites' identity.
In terms of value, you could perhaps sell it for up to $2000 to a motivated end user who appreciates the identity and wants to go with it.
Good luck,
