Why is Esperanza unhappy with her family's new home on Mango Street?

Her family shares the home with Lucy and Rachel's family, so Esperanza does not feel comfortable there.
Her family used to live in a far nicer home on Loomis Street, so she is sorry that they had to relocate.
The house is small and in poor condition, so Esperanza is ashamed of it.
The house is larger than all of the other homes, so Esperanza feels out of place in it.
