Værelset var helt ok, men et ikke bemandet hotel, er nok ikke lige os. Beliggenhed er heller ikke for os godt, for langt til byen, når man nu skal væk fra hotellet, når man skal have aftensmad. For dissideret billigt er hotellet jo ikke. Morgenmaden var bare helt ok, stort og bredt udvalg af morgenmad. Hilsen fra Lillian og Svend Erik.

Skuffet 3 stjerner er højt vuderet

Den seng jeg sov i de 2 nætter var ret dårlig betydelig blødere og sammenfalden end min hustrues. Drr var ingen service og ved morgenbord skal man selv ryde af.

Hotel eller vandrerhjem?

"Hotellet" mindede mere om et vandrerhjem. Rigtig god morgenmad Forholdet mellem pris og kvalitet er ikke i orden!

Pænt hotel i kedeligt område

Pænt og rent hotel med fin morgenmad. Beliggende i udkanten af byen i kedeligt område. TV kanaludvalget er dårligt, havde f.eks. ikke TV2. Røgluft trænger ind på værelser da der ryges lige udenfor.

Ok ophold. Nemt selvbetjening vedr. indcheckning via kode. Fin morgenmad. Skuffende gammelt badeværelse, især da hjemmesiden skriver moderne badeværelser. Der er ikke helt styr på udcheckning. Rengøringspersonale kom ind på værelset, selv om vi havde til kl. 11 til at checke ud.

Ganske udemærket hotel i rolige omgivelser. Det fungerede fint med sms og koder. Morgenmaden kunne være mere frisk. Kaffen var ikke nybrygget og brødet virkede lidt tørt… Skønt med fri adgang til kaffe/the mm.

For det meste godt

Elsker for det meste 6400, men denne gang var der ikke TV2 på tv’et, kun DR og tyske kanaler. det er ikke godt nok; slet ikke i et comfortværelse, som man har betalt ekstra for. Brødet til morgenmaden virkede gammel, fra dagen før. Det var ikke godt. Ellers fungerede det godt
