Laura is a very friendly host. She will contact you to know more about you, and be pendent of your arrival time. You can contact her if you have a question. I really enjoyed my time there. It is very close to Park Güell and the view is very nice. I felt that the room was spacious and everything was clean. There are a few bodegas and mini markets around so you can buy food, cook something in the kitchen (only if it's vegetarian food). 👍🏼
Keep in mind that you can use the mechanic stairs to go up there. I really recommend it.
