Extremely Hot With Poor Ventilation
Most of the windows on the 1st floor do not open, and there is only one main window on the 2nd floor, so no cross ventilation.
Do not stay here in the summer. It is unsafe.
Our Eurostar had severe delays so we didn't arrive until after midnight. It was an extremely hot day, and we arrived to find all of the windows closed and the flat boiling hot. We tried opening what windows we could, but it made no difference in cooling down the flat. We were forced to find a last minute hotel, as the flat was so hot it would have been unsafe to stay there. It was easily at least 10 degrees Celsius hotter inside the flat than outside.
Given the hot weather, I was extremely disappointed that the host did not take steps to make the sure the flat was inhabitable, other than to provide extra water in the fridge. The windows were left closed and no fans were provided.
I messaged both the host and airbnb support immediately that night via the Airbnb platform's refund / cancellation feature explaining the problem, why I had to vacate the flat for the a last minute hotel, and requesting a refund since it was not safe to remain in the flat, but I have been refused a refund for my booking.
