Erika's apartment was absolutely perfect for our family. Lots of space and an awesome location in Roma. The speedy wi-fi, filtered water, and toiletries were well appreciated. We cooked many meals in the apartment and the kitchen was well-equipped for our needs.
Our only complaint, as someone else mentioned: the cleaning seemed rushed before our arrival (floors seemed a bit dirty, dark hairs, etc.), but the apartment was otherwise wonderful so we weren't too concerned about it. It also did get pretty chilly in the apartment at night; not a big deal for us, but our baby had some trouble sleeping a couple nights - may be something to consider if traveling with a baby.
Otherwise, I should also mentioned we felt 100% safe in the neighborhood and the building. The extra security of a doorman really made us feel at ease. We hope to return to Mexico City and stay here again some day!
