I had a very enjoyable stay at Casa de Aire. My total stay was three weeks in this unit. I was pleasantly surprised when I arrived. The unit was just as described. The owner did a fantastic job with the pictures and description. The TV in the living room and microwave in kitchen were not in the pics but are in fact in the unit so that was nice. The staff was very nice and accommodating. I would definitely stay here again.
The unit does not have A/C, but as someone who loves their A/C, it didn't bother me. There is a tower fan in the bedroom that definitely helps at night. As the listing says and other people have said, you are close to the Zona Rosa nightlife. If the bedroom window is open, you will hear it. Even with the window closed, you can still hear some of the noise, but when I had the window closed and fan on, I didn't even notice. If you are a light sleeper or not accustomed to living in a city, I would suggest bringing some ear plugs.
