TL;DR: Valentino was excellent, and I'd hire him again in a heartbeat.
I had some hesitations about hiring a plumber, after all the stories I've heard about plumbers charging exorbitant prices. For my disconnected kitchen sink pipe, a couple plumbers quoted me very high prices. When I came to Valentino, he charged me a fair price that was much less than the other two quotes. And moreover, he came on time and got the job (which actually wasn't so simple) done well.
Super nice, super professional, and super honest. Hands down, I'd hire him again, and would recommend him to my friends.
