We really enjoyed our time in Vienna. The apartment was in a very good location, only a short walk or tram ride to the main ring road / museums quarter. The tram stops very close to the apartment which was great for luggage. Supermarket/bakery and restaurants close by (recommend the Vietnamese place at No46). The apartment was warm when we arrived and reasonably clean. Ample space for two. Basic utensils so could prepare a simple meal and breakfasts. Not sure how to work the coffee machine though. As mentioned by others in a previous review, the boiler is a little noisy but the bedroom door could be closed over to help this. One side of the bed had creaky slats but otherwise comfy and spacious. Other minor point was the drain-smell in the bathroom but the shower was decent and plenty storage space.
Arranging check in was straightforward via phone upon arrival. We were let in by a housekeeper. Check out time was established relatively last minute but we were able to store bags in another apartment until our evening flight which was helpful.
Overall, this was a very good value and well located place to use as a base.
