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

Helt topp, nydelig rom, herlig basseng og badstue. Bilheis var en ny opplevelse for meg, men fungerte strålende. Byen hadde mye fint å få med seg av arkitektur

Det var en tysk skoleklasse på hotellet gode opførte sig som vilde dyr indtil kl. 22:00 natten gik heldigvis godt. Men jeg var nød til at gå en tur om aftenen for larmen.
Og bruseren på værelset 212 kommer der kube 2 stråler ud af.

Eneste lille ulempe: få ordnet det knirkenden gulv på værelse 207 ;-)

Vi havde et værelse på 1. Sal, fin trappe samt elevator. Badeværelset var næsten nyt og godt. Et par gode senge, gulvet knirkede forfærdeligt i den ene side af Værelset. Gratis kaffe og andre valg fra fuldautomatisk maskine med kværn og friske bønne. Rigtig god kvalitet. Morgenmad havde et fint udvalg og det smagte fint.

3 nætter i dobbeltværelse med to senge. Udemærket værelse og behagelige senge. Godt og rummeligt badeværelse. Manglede køleskab på værelset. Morgenmad Max 2 stjerner. Tørt brød og meget begrænset udvalg.
