Godt værelse på praktisk hotel

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.

Godt til prisen

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.

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.
