The staff are very friendly and helpful. The rooms are clean and spacious, if a little basic. The hotel is good value for money. The location is very good - close to a U-bahn station that takes you into the city centre within a few stops. No wi-fi in the rooms but you can bring a cable. You will have to pay for internet access in the rooms and for the wi-fi in reception.

This was my 14th trip to Vienna and the first time i tried Delta Hotel. At first i thought the location would be really bad but it turned out to be really good. The subway station is really close, there are a lot of restaurants and "Konditorei"s around, a shopping center, a lot of other shops (C&A, Mango, BILLA, BIPA, H&M, Salamander, Deichman, Intersport, Muller and so on). It is 4 stations away from the Stephan's Platz (The Ring).
The rooms are clean, big enough, the bathroom is just great, with a really god shower. It doesn't have a minibar and that's a minus when it's hot outside and you want to have some cold drinks in the room. Breakfast is really tasty and rich BUT the big problem that bugged me a lot was the "breakfast-staff". They were coming to take the plates from your table even before you finished your food, and they were very insistent. I usually spent 10-15 min at breakfast and so did everybody else so it wasn't a problem of a too crowded room... and half of the tables were empty at almost anytime.They also arranged the cutlery really loudly, in the middle of the room and they were always angry and flopped the dishes and napkins. Breakfast was really loud and annoying.
Also the parking isn't free, you have to pay 15euros/day.
Another thing that irritated me was the Internet. You had to pay 2,5 euros/30min or 4 euros/1h or 6 euros/2h. BUT the internet was SOOOOOOOOOOOOOOOOOOO SLOOOOOOOOOOOW...in half an hour i could check just one mail and i payed 2.5 euros for that... .

Nice hotel in quiet area, close to favoriten strasse with many restourants and shops. Metro station U1 is about 200m from hotel, and 2 stop is Karlsplatz and 3rd station is Stefansplatz. Rooms are very clean, beds are good, just pillows are to tiny for me. Bathroom is comfortable, staff is helpfull and gently. Breakfast is nice and diversiform, only one thin is bad, and that is juices. They are terrible (pure chemistry), but other things in breakfast are very nice (they have pancakes)!!! In summary hotel is good and I am satisfied.

This hotel is a little off the beaten path. I had read reviews that warned how unsafe the neighborhood seemed for a woman traveling alone and arriving at night. I definitely felt unsafe although I arrived with a group. Once you see the area in the daytime it is not so frightening. That being said the hotel is very nice. I did not get the breakfast which was rather expensive but we were able to eat at a nearby mall very inexpensively.
