Marlies and her sister were nice guests who were easy-going and kept the house clean. I m really sorry, they were a little unsatisfied with the room and my conditions. I told them, there was a key, but I couldn't find it at their arrival, because I m often abroad and had put it aside. They were understanding and since nothing s been stolen and we have enough privacy in my house, they seemed to be ok with it.
Besides that, in my add, I m renting out 'one room' with 'one bed'. The fact that we have 'two' bathrooms in the house doesnt mean necessarily that guests will use one of it on their own. we re a flat share of four people, each time two sharing one bathroom, I guess things could be worse. So here I would just simply recommend to ask before. I also have a very expensive mattress in my bed, so I guess the comfort issue is a matter of perspective here as well. Other than that I was happy to have them and would have them again any time.
