Hola buenos días, como dice el compañero es mas fácil acudir a una web de viajes de tu confianza o incluso a la del hotel, pero el verano pasado estuvimos paseando por Noruega y esta cadena "Scandic", nos dio los mayores sinsabores. Suerte.

scusa, vista solo ora la richiesta di informazioni ... suppongo che non ne hai più bisogno. saluti
