The main issue with this accommodation is that all doors to the home use exit locks, meaning guests cannot enter or exit the home without the use of a key. According to the host, herself, not even the police or fire department can knock down these maximum security doors - which is dangerous and patently ridiculous.
What this means for the guest is that if, for any reason, you misplace your key, you cannot exit the home. If you drop your key and cannot locate it because of some event that has obstructed your vision (like smoke), you cannot exit the home. If there is an intruder and your are understandably not thinking straight, you cannot exit the home. If the host leaves the home and does not give you a key or tell you where you can find one, you cannot exit the home. You’re trapped.
That last scenario is what happened during my stay. It obviously caused problems between the host and me in what was otherwise a solid stay. I cannot in good faith recommend this home to other travelers.
