To start with positives, the host was polite, responsive & accommodating. He arranged early check-in, communicated throughout our stay, and the apartment was clean. Under diff circumstances, I’m sure it would be a nice place to stay. Unfortunately, our experience was disappointing, and we left after the first night. We arrived in Lyon during a heatwave and the apartment was not equipped to handle the extreme temperatures. Although fans were provided in each bedroom, they were old, noisy, and ineffective. At 23h, the temperature inside was still 29.5C (85F) - warmer than outside. The beds were made only with comforters & no top sheets, so we slept without covers.The kitchen was also not well suited for a large group. The only refrigerator is a small mini-fridge, despite the apartment accommodating up to 10 guests, making it hard for families or groups planning to cook. The Wi-Fi also did not reach bedrooms near the kitchen — an extender would help.Our group included three generations, from a 16-mo-old to 82 yr old grandparents. Because of the extreme indoor heat, we did not feel it was safe or comfortable to stay.The host kindly offered to let us return during cooler weather, which we appreciated. However, traveling from California, that was not a practical solution or a substitute for the partial refund we requested. Sadly, I would not recommend this apartment for families with young children, elderly, or groups wanting to cook, esp during hot weather.
