Nice host but bad experience.
We stayed in the apartment for one week and it was very cold. There is an AC that is used as a heater but it's not sufficient for the apartment (the AC filters should be also cleaned as they were full of dust). In addition, the house gets extremely humid so it makes the cold even worse.
This is understandable due to the location but a better solution has to be found not to make the host suffer cold.
In addition, on the last day of our stay, we discovered a big mold stain on the wall hidden by the couch. Mold is toxic and it causes respiratory illness, and we got very sick during this trip (probably due to the mold in the house, the humidity, and cold weather).
Most of these problems can be mitigated with a professional dehumidifier and a better heating system.
