Good communication. If you have any problems Petra and Chris are quick to help. The main room is very spacious and the apartment stays quite cool which is nice if you are staying in Vienna during the hot summer days. The kitchen is small and doesn't have much counter-space so stick to easy meals if you plan on cooking. Apartment is also on a quiet street so noise is minimal. Location was fine but might be far for some. I come from London so everything seems close in Vienna! However, it is convenient as you can pick up tram lines 46 and 9 from Feßtgasse on Thaliastraße or alternatively take the 2, 9 or 44 from Johann-Nepomuk-Berger-Platz. Both stops are just a 2 minute walk from the apartment. The U - Bahn also isn't too far. You can reach the stations on Josefstädter Straße and Thaliastraße by foot but will take you about 15 minutes or you can just jump on the tram to reach them. There are plenty of food stores around. Apartment is also next to the Ottakringer Brewery which was having weekly festivals during the summer so if you fancy some good beer and there is something going on it's wort checking out. Good value for the money and what you see is more or less what you get. No tricks! Would stay here again if I am in Vienna.
