Studio Apartment in Mexico City

Hi! I'll be arriving in November and I'm looking for a studio or loft in del Valle, Mixcoac or Coyoacán (or something nearby). My budget is around 15K. I'll be in the city until the end of April, but I'm flexible with the dates. I could also be interested in sharing an apartment with roommates, depending on the conditions. Or if someone else is also looking in those areas and would be interested in sharing an apartment, write to me! Sometimes it's easier to find something for two or three people and split the rent. Thank you very much!
