Rent hike for residential unit must not exceed 7% yearly

Dear PAO,

I am a 4th year student in one of the universities along Recto Ave. in Manila. I am just renting bed space for P3,500 a month in one of the boarding houses near our school, considering the meager allowance I am getting from my parents. My problem began when my landlady raised the rent by 5% last January of this year, two months before our summer vacation. She again raised the rent by another 10% when classes resumed in June. I am just wondering if this is allowed by law?
