I would like to start that the owners are amazing hosts! Great interaction! Apartment is cute and very clean.
However, it is very important to note, it is very hot. The apartment is a ground floor apt with the only "window" being a door that opens to the sidewalk of a busy sidewalk. So, basically there is no window to open at night and NO AIR CONDITIONING that works. They have one, but the exhaust vents to the inside, thus making it hotter than not having any air conditioning at all. They need to vent the air conditioner to the outside, but it is not.
The apt has a fan, but it just blows 85-90 degree air onto you.
I travel around Europe a lot. I understand Euro Heat and lack of A/C, but I would expect to be able to open a window for some fresh air.
Again, hosts are great, but people need to know it is going to be HOT. When A/C is vented, life will be much better
