Both are grammatically correct, but mean slightly different things. “What place is it?” is more of an open inquiry, whereas “What place is this?” indicates that there are only a limited number of options – say three or four places – and the answer should be one of this group.
Good question! Both are correct depending on the situation. “Who” indicates that the answer must come from a limited number of places – places that may have already been discussed. Example: Which of all the places you have visited is your favorite?
The answer to “What” has unlimited possibilities. You don’t have to choose between options already discussed or understood. Example: Where [of all the places in the universe] do you want to visit next?
In a word, “who” requires an answer from a limited number of elements. “Which color do you prefer, red or orange?”
“What” asks for an answer of an unlimited number of items. “What’s your favorite color?”

Which place is correct if you look at only one place.
What if you have multiple options.
Depends on the context
If you are already there and you don’t know where you are, you can say “What is this place?” “Where am I?” “Where are we?” “Where is he?”
If you’re traveling there, you can say “Where are we going?” “Where are we going?” Or if someone says we’re going out, you can say “Where to?” “What place?” “What place is it?” » English is very flexible.
