We stayed for four days a friend and me at Irene's house. At first, Irene let us to check in early since our flight arrived at 12:00. At our arrival, Irene showed us the house and made us feel really confortable. She gave us indications for metro tickets and resolved our questions and doubts.
The room is really big, well decorated and clean. The house is well conected to the S-Bahn, which leds you to the city centre in 10 mins.
We recommend this place to anyone and, if we have the chance, we would like to stay again at Irene and Christoff's.
