Hotels can now edit its services and amenities in the "Hotel attributes" section of their Google My Business account. Google My Business was having issues with hotel edits earlier last week and it might have been related to this upgrade? In any event, now hotels can login to Google My Business to modify this data.

Google has an updated help document on how to update this information for hotels.

Just to be clear, this is not available on the mobile app, you can only edit this information from your desktop browser.

Here are some screen shots of what you can edit from Matt Heffner in the Local Search Forums.
