Rita's house2
Rita's House is a location in Mako Mermaids. It is where the school principal, Rita Santos lives. She lets LylaNixie and Sirena live there, only if they follow what she tells them to do and they agree. The house appears to be by the ocean and very modern. There is a bookcase in her house which leads to the secret Grotto filled with mermaid artifacts and a water opening which leads out to the ocean.
