Hello,

Would you please tell us what is the source of the data you are using?  You might want to know that most websites that list businesses have strong copyright restrictions against re-using their data on websites like ours.

Some parts of your edit raise a few questions.

Take this hotel in Berlin

The phone and website were properly set, as contact:phone and contact:website respectively.  It looks like you have been adding "phone" and "website" tags duplicating those values.  (Also, for the website, you should not just time the domain, but a valid URL including the https:// part)

Same for the hotel in Valencia (you added a second email address on top of the one that was already on the database).
