I found Peter's carpet cleaning service through a YP/Yelp search and sent an e-mail to get a quote. Peter Tam himself responded quickly and quoted me a great price for bedroom, living, and dining room carpet cleaning which was proportional to the effort required (instead of a blanket response).
He arrived on time, was very professional and courteous, and took pride in his work, leaving our carpets cleaner than ever. He wore shoe-coverings and was completely able to work around the awkward position of our apartment unit, relative to the entrances.
