Eva's place was fantastic! We absolutely loved our stay in Vienna helped in large part by our experience of the home. Bottomline first for tl;dr - for a couple on sightseeing trip/holiday - this home is ideal. Book it!
The best part of the home is the location. It's down the road from the 3 major museums, a 10 minute walk to the Hofburg and 15 minutes to the Opera. This means that with the exception of Schonbrunn, you will never need to take a cab or any public transport for 75% of your sightseeing!
In addition, there are good restaurants around as well as a supermarket for quick fixes.
The hosts are nice and very responsive, accommodating and helpful. There is a plethora of advice, tips and maps - not just Vienna but also outside. Huge TV in case you can't get away with cable TV channels and some books as well.
Finally, it's appropriately priced and I ended my trip not feeling like I could have paid less. Honestly, would recommend to everyone!
