The road can definitely be a problem for everyone who is coming with a really low car, as Jasper's one. Thanks for the review, I am going to write this detail in the house description in the case someone else would plan to come with a similar kind of car.
Unfortunately the bumps on the road can't be removed as we put them there in purpose: they help rain-water to pour out into the fields in order that heavy rain would not dig too much the road.
I thank Janka for her review and for having underlined all the mistakes in my description which I have amended. There are no Tv and no washing-machine in the house and the boxes of these facilities were selected by accident. By contrast there are 3 bedrooms in the flat, but we decided to rent just 2 of them (we thought that 5 beds were enough) and we use the third room as a storage room which is of great help in dealing with the rentals. I amended this part as well.
Following Janka's recommendation we are planning to make some work to bring hot water in the kitchen (among all our guests no one has never complained about it before and I have to admit that I barely see any connection between hot water from the sink and cooking. It is really useful to wash the dishes though and that s why we plan to make this improvement).
I respect Janka's opinion, but I reckon that what was "creepy" for her is charming, relaxing and peaceful for others. The "locked doors" at the ground floor are the entrance of the garage which is full of old dusty pieces of furniture that I don' t see why should interest the guests. The first floor is not occupied since it is our private flat and I have always thought that guests prefer to have their privacy and having full access to the garden than sharing the space with us.
