The apartment is lovely, full of light, on top floor (no lift) in a very nice area with lots of shops and cafés. A couple of supermarkets are also very near. Wi-fi works perfectly. We did not meet Ulrike but her father welcomed us into the apartment. Transports are near but if you like walking, as we do, it takes only about 20 mins to reach the MuseumsQuartier and the centre is not far from there. Communication with Ulrike was very easy, she answered quickly and exhaustively to all our questions and gave us precise instructions and precious advices.
