The words of Massimo (whose mother language is not English - as is mine) are so eloquent that a response in kind will result in only the most feeble of outpourings. Of course the couple are the dream of any renter: quiet, undemanding almost to a fault, clean, generous, full of the best of humanity (this sounds like a paid advertisement but it isn't) and interesting - all of course beckoning the promise of further contact and hopeful life-long friendship. It goes without saying that it would be wonderful to host them again but I fear they must explore other sights and sounds as all travellers must do. They possess the right kind of curiosity that never intrudes but reveals an inner desire to learn all things, if possible. Certainly the best renters ever in my experience. The only bad thing is that such a wonderful experience will only tarnish all further ones. Love to you both and let our paths cross again - soon and often!
