We are a married and live in NY. Both in our mid thirties.
Claudio's parents stayed at my apartment, as they were visiting from another country, but I had all of my correspondence with Claudio. He was very polite, and responsive to me during the week his parents stayed. I know that Claudio spent a good amount of time at my apartment with his parents, and overall they were very good guests, respectful of the apartment, and left it in tidy condition when they left.
