Thomas, i am sorry to hear these words. I apologize for any inconvenience you had. Firstly, i believe the pictures are very explanatory about the size, amenities and services of the villa. All guests we had said the pictures don't do justice for how nice our home is.
We take into consideration all reviews, because we want to keep our standards very high, so we will take a look at the sofa bed.
Secondly, you paid around fifty euros for four people, so it is less than fifteen euros per person. The service fee you paid is charged by Airbnb, not by us. We calculated the price in order to cover our costs, heating costs, water costs, cleaning, airbnb commission and others, and I am confident to say we don't do much profit, because we want to offer the best experience for our guests. For example, we had to pay extra cleaning services after you left because there were peanuts and seeds all over the bedroom, however, because we don't want to increase the price, we didn't overcharge you. If you research the prices in Sinaia, we are one of the lowest (considering the offering).
Again, I am sorry you didn't enjoy our villa as all our guests did. Wish you all the best!
