In Harry Potter and the Order of the Phoenix where does Harry stay in the summers?

Answer 1

Number 4, Privet Drive, Little Whinging, Surrey, UK. At the begging of the first book he lived in the wardrobe under the stairs but as the story develops he moves to the little room in the second floor.

Answer 2

He spent the first month of the summer at the Dursleys until he got a letter saying he's expelled from Hogwarts. Then a group of members of the Order of the Phoenix (the most important, and the ones present in the movie - Tonks, Lupin, Mad-Eye Moody and Kingsley Shacklebolt) came to his house and took him to the Order of the Phoenix's headquarters - Sirius' home, where he spends the rest of the summer, with Hermione, Ron and the Weasley family.

Answer 3

Until his seventh year, he is either at Grimmauld Place, the Burrow (Ron's house), or at Number 4, Private Drive with his aunt and uncle.
