Travellers will love staying at Guillaume's flat. It is a comfortable, clean, well set up place from which to explore Paris. The location close to Gre Du Nord and the Metro line makes is super helpful. The neighbourhood is not posh, but has all the amenities needed. Guillaume himself is an attentive host, checking in with you throughout your stay to make sure you're taken care of and offering above and beyond help if required. I highly recommend staying at his flat.
