Luisa (and her boyfriend Christian) made our stay in Berlin the best possible: we were able to reach the house without any kind of problem (2 U-bahn and 1 S-bahn metro stations 5mins away), the house was perfectly clean, and well described in the announce (I may also say that it is really beautiful with a lot of personal details included in the decorations that made it also even more interesting that it seems). The house was easy to reach even during the night, even when we went to some clubs and we had to come back really late (we profited of different metro combinations to get back and this was really useful). Luisa helped us also when the weather started to get really cold, until offering her own clothes as we were unprepared to a drop of 10 degrees in 1 night, and we must really thank her for all the help provided. Our experience can only be said as perfectly satisfying thanks to Luisa (and Christian) and her house.
