You were a delight to talk with and I thank you for your kind appreciation of my restoration of Casa Metzli.
Mérida's weather has been unseasonably hot, even for Yucatán, this year, and I am sorry the fans, of which there are 5 in the house, were not sufficient in keeping you and your husband cool. Unfortunately, with the cost of electricity in Mérida, I cannot rent Casa Metzli for such a great deal and supply air conditioning throughout the house... For this reason I have air conditioning in the bedroom only.
My only slight disagreement here is that the house is located closer than 30 min from the center (please refer to the image taken from (Hidden by Airbnb) maps), so the walking time is suggestive and depends on many personal factors.
I hope that you and Helmut enjoyed the beautiful city of Mérida.
Wishing you the best,
