Hello Laura, I am deeply sorry for your unpleasant experience at Casa San Miguel, I wish I've had the opportunity to put you in a more convenient bedroom for you, wish I had known during your stay.
You are correct, those two bedroom (the one where you stayed and the one next to it are built with drywall, which is the strandard on construction), the other three bedrooms were built like the old fashion way, with bricks and cement.
All beds in each bedroom are new, orthopedic and Selther brand.
Those locked rooms that you mention (two living room and dinning room) are open to the guests from 6pm -10pm , where I offer a free cocktail, which allows the guests to get to know one another.. these rooms remain locked per Airbnb recomendation, as I have highly valuable art pieces in those rooms.
Lastly, I totally disagree with your comment on the two new bedrooms, which are in the house, not divorced from it. This was done with the intention to offer different rates to the guests.
Remember I showed you the five bedrooms I have listed on airbnb.
Once again, I am deeply sorry for your bad experience. I aim to please my guests and show the beautiful home where I live.
