Pros:

Schönes, gepflegtes, ruhiges Hotel in bester Lage oberhalb der Mühlbrunnenkolonnade. Mit dem Schlossturmlift ist man in 5 Minuten in der Fußgängerzone. Sehr große, schöne Zimmer im Schloss-Stil, feines, abwechslungsreiches Frühstück mit allem, was man sich wünscht. Nette Frühstücksdamen, hilfsbereites, kompetentes Personal an der Rezeption. Im 1. Stock kühl trotz 36° Außentemperatur, leiser, effizienter Ventilator im Apartment samt Fernbedienung- funktionierte perfekt! Wir buchen beim nächsten Karlsbad Besuch wieder Hotel Ontario!

Hotel godny polecenia
Pros:

Bardzo dobre i urozmaicone śniadania. Lokalizacja świetna, w samym centrum. Jednak dostanie się do hotelu pieszo wymaga trochę wysiłku ze względu na położone na pewnej wysokości.

Cons:

Duży i wygodny apartament, pomimo braku klimatyzacji podczas upałów nie było zbyt gorąco. Do dyspozycji dwa wiatraki.
