Erich's place was great. It was close to everything, and easy to get to multiple train lines. There is a grocery store on the corner, which is very helpful, and plenty to eat near by. Erich's place is directly across from Museum Quartier, which makes it relatively simple to get anywhere in the city. The space itself was bright and clean, and the layout was very functional. The washer and dryer didn't work during out stay, but everything else was great. We had a problem with the coffee maker, and Erich was quick to assist and fix the problem.
We would definitely stay again. It was perfect for our two families to have some time together in Vienna.
