This is a very good, basic hotel: spotlessly clean (the room was cleaned daily), quiet, a bigger room and bathroom than expected, adequate breakfast, very good brewed coffee, in a very good, safe, quiet location close to the VAL terminus, Ubahn, tram lines, and walking distance to St Stephen's and other sites. The staff is helpful if you need anything and polite. There are 3 grocery stores less than 5 minutes away which was very convenient (though no refrigerator in the room). I highly recommend Dan's and will stay there during my next trip to Vienna.
