My first comment just concerns my personality: I love natural light. In a trullo, you need to switch on the lights at all times because it has hardly any windows. It is just dark. In winter, when we went, it is borderline depressing.
I have 4 main criticisms regarding the way Maria and her husband manage their place.
1) when we arrived we had to fill out a rental agreement. It is the first time, I have had to do so when booking a place with Airbnb. There was as well another rental agreement for the garage that we reserved. I had the feeling that the owners were renting their trullo but had no trust whatsoever in their guests. The owner of an Airbnb can check who they are renting their place to and decide if they want to rent it or not to the person making the reservation.
2) we arrived on December 26, a Sunday. We asked if anything was open. The answer was a sharp “no”. I am perfectly aware we are living through difficult times, but conveying one’s own anxiety to one’s guests is not the best way to welcome them. Bars and restaurants were open, as well as souvenir shops. There were many Italian tourists enjoying the stupendous illuminations of Alberobello.
3) In a Airbnb, in the kitchen there is usually some spices (salt and pepper), oil (in a province where olive oil is one of its main productions), vinegar. There was none of the above. It enables the guests to do some cooking when they do not want to go out. The owners could add 5 € to the overall price. It would make a huge difference for their guests.
Instead of spices and oil, we had towels and sleepers with the logo of the trullo. All that looks nice, but it does not replace the basics a guest should find in a kitchen.
4) Finally, I would not recommend a trullo in the winter. It was cold.
