I appreciate your comments, and I would like to clarify the following:
Indeed, my husband and I did everything possible to make your stay pleasant and enjoy to the fullest. We traveled from the north of the country to give you the apartment and make sure you feel safe and happy. However, I consider that qualifying my apartment as in a noisy area, belittles the quality we are offering. I clarify that the noisy area is located on 12th street corner with 5th Avenue, where are the clubs and bars. My apartment is located 7 minutes from the beach (by bicycle, at least is the time I do).
The noise of vehicles and motorcycles is the same as ALL other departments in the area, they are heard.
The noise that was heard at night refers to the cistern that we have installed for the entire building. Turn on when there is not enough water in the city and it is approximately 20 minutes. In this topic, I will ask you to review it, to see if you can make a modification to reduce that sound, but you can not change the entire cistern.
It is not specified in any part of my ad, that I have to deliver double key to a person who is renting the apartment to me. I think it was your initiative, to give your partner independence. The ad says verbatim "familiar". Usually, families go together.
Sorry I could not ask the neighbors to turn off their Wifi because you are hypersensitive. The only thing I did was install the modem, near where you recommended me to do it (fortunately, it was in the process of being installed).
I hope that soon I travel again to Mexico, and I recommend Holbox. That place I think is what you need to relax: There are no streets with vehicles and there is no internet.
