Don't go there!
The place is underground and has no windows !!! Only exception a small window in the kitchen that overlooks the dark back of the building!!
The ventilation system is bad so the smell of mold was so potent that it made it impossible for my 2 kids and myself to sleep there.
I called the host immediately. He was extremely rude over the phone telling me that this was my problem and that I should have noticed from the pictures that there are no windows!!! He has denied any reimboursement, even part of it.
Worst experience ever.
