    Sehr freundliches Personal, tolle Lage und schöne, großzügige Zimmer – wir haben uns wohlgefühlt!

    Die Lage des Hotels war top – sehr zentral und trotzdem angenehm ruhig. Das Frühstück war eher einfach, aber für einen Aufenthalt von zwei Nächten völlig in Ordnung. Insgesamt waren wir zufrieden und können das Hotel weiterempfehlen.

    Ein kleiner Verbesserungsvorschlag wäre, noch etwas mehr auf die Staubentfernung zu achten. Da ich eine Stauballergie habe, ist mir das besonders aufgefallen.
