Rental URLs

As Roland said, a link to the area in question would enable us to check wether the tags are apropriate. But I'll try a few guidelines here :

• If there is a website talking about a house, wether it is about renting, history/culture or similar, it is appropriate to add a website tag on the building.
• IMHO the website would need to be a permanent one : a link to a Craigslist or estateagent page seem inapropriate to me for example.
• Any kind of subjective rating is not osm-apropriate : an official Michelin star rating might be ok, but a Tripadvisor or Yelp rating isn't.
• There are other things you could tag: wheelchair access, internet, pets, smoking might all be relevant to a potential renter, and good for osm (just remember to edit osm again when those policies no longer apply).
