From distance, it's a very beautiful looking jumbo jet. As you get closer it seems like you are boarding the aircraft via remote stand, After looking for some research inside this 747 as a hotel I couldn't find any images what it looks like.

This is not the only aircraft that's turned into a hotel. In mid 2010's a McDonnell Douglas MD-11 was converted into an apartment for Airbnb.com it looks like living inside the MD-11 for life.
You can now book your room on the Corendon website for a large fee to stay inside a Boeing 747 aircraft. The aircraft is located at Schipol Airport next to Ibis Budget. Once you walk through a tunnel, you should be able to see the Queen of the Skies looking right at you.
