Guillaume's flat was brilliant for visiting Paris. My girlfriend and I visited Paris for 4 days and found the transport links to the landmarks/attractions extremely useful and Guillaume was an extremely good host. Guillaume's flat was clean and just the perfect size for a couple to use for a few days in Paris. Guillaume helped us with anything we needed including printing tickets out for us that we desperately needed to print. He made us feel very welcome and I would strongly advise anybody to stop in Guillaume's flat if they are visiting Paris (we certainly will be coming back).
