Constanza is a great host. She will be available anytime to ensure your stay is comfortable; for instance, we asked her politely to change our bedsheets because they had dog hair and I am allergic, and she did it without hesitation. Communication is easy, and she will suggest things to do around Condesa, one of the best neighborhoods of CDMX.
It is fair to note that the apartment has a strong cigarette smell, so this is an excellent option for you if you have no problem with it.
