The hotel has big plus and big minus in it's location. The plus is that they are within 10 walking minutes from the Ringstrasse and 8 minutes from the Naschmarkt. The minus on the other hand is that it's about the same time to get to the nearest metro station and about 6 minutes to get to tram station, so if you have no problem with walking a bit, you can get to central locations by foot, but if that's a problem, you can't just hope on public transportation close to the hotel. Also, the rooms were really big and that's always a nice plus, since too many times the rooms are just tiny. The staff was very helpful and all could speak English. Breakfast was a bit mediocre, probably the worst breakfast we had in our trips. It was decent, but not more than that. Also, as many said already, the breakfast room gets really crowded and it's hard to find a seat. We spent there three nights and all three times shared our table with another couple and once needed to wait about 10 minutes to do even that, since there was no place to sit. Bottom line is that I do recommend this hotel. It's cheap, rooms are big and close to the center.
