BEWARE. SECURITY ISSUE!! There is a secret under-the-stairwell passageway between the host unit and the guest unit with no lock on the guest side. There is just a handwritten sign taped up to the cabinet door saying that it is "not an entrance". The host's husband actually used this passageway to enter the guest unit shortly after my arrival even though there is a regular outside door at the top of the stairs. He was there to check on me to make sure everything was okay. That's customary, but popping through a creepy unlocked secret passageway is definitely not customary. I was totally unnerved and left immediately afterwards to find another rental. Agnes pointed out that there is a bolt lock on their side for "their security". Swell. That's not much comfort if you can't also lock it from the guest side.
The unit itself is cute and well furnished, and it was in a good location. If it wasn't for the security issue with the secret passageway, I'm sure I would have enjoyed my stay. I'm hoping the host corrects this security issue by installing a bolt lock on the guest side and not using this passageway when a guest is in the unit. That would solve everything.
