Frühstück 10 von 10 Sehr nettes Personal beim Frühstück. Die Lage des Hotels war für uns als Familie optimal...U Bahn in der Nähe um schnell in der City zu sein und Abends zu Fuß an den Strand. Die Zimmer waren völlig ausreichend und praktisch ausgestattet.

Not a 4-star hotel (anymore)

Pros: Nice location if you want to be close to the beach. The room was spacious and had several big closets to keep your clothes organized.

Cons: While the room was big, the bathroom was outdated, smelled of mold, and there was rust colored ring around the bathtub drain which made it uninviting to sit in. The joint where the bathtub protective door opened was covere
