I really enjoyed my week-long stay in Ulrike's apartment. Ulrike is a very communicative and flexible host, allowing me to check in much earlier than normal because of my flight schedule to Vienna. The apartment itself is very spacious with high ceilings and wide doorways, has all necessary amenities (including a spacious kitchen with a dining area and a washing machine), and is very well situated in close proximity to the Innenstadt, the Museum Quartier, the shopping district along Mariahilfer and around the Westbahnhof, several tram, bus, and U-bahn lines, and a wide selection of nice restaurants, cafes, and grocery stores. Very highly recommended.
