I have no hesitation recommending this apartment, it is spotlessly clean with everything that you need for your stay but what I must emphasize is how wonderful the location of this apartment block is, within 5 minutes you can walk to the open air market which serves all sorts of delicious food including breakfast, at Karlplatz you can get on the underground and then round the corner is the Opera house, this area has everything and total access to the trams and buses.A very good place for breakfast is Cafe Market in Karlplatz, Omer served us and the food is delicious, highly recommended.Cafe Central further in town sells the most stunning assortment of cakes, we saw the Barber of Seville at the opera which was wonderful, its not cheap but you can queue for less than two hours on the night of the performance and they allow over 500 people in the standing areas for 3 to 4 euros,bargain, well worth the wait. Vienna is a beautiful city and we thoroughly enjoyed our stay, book this apartment, you won't be disappointed
