Todo, pero por sobre todo... la atención de los dueños

Decirle algo que no me guste es como buscar la quinta pata al gato.

Las camas están 10 puntos. La vista aunque lateral muy buena. La atención de 10.

Cualquier problema que surgiera siempre fue bien atendido por los dueños. Por lo que no hubo nada que no me gustara. Lo pasamos muy bien.

Lo esperado es lo que encontramos, excelente todo.

El desayuno excelente con varias alternativas así como jugos, yogur, tartas, etc., y un rico café. La ubicación del hotel es privilegiada, solo a metros de la bajada a la playa. También, la atención del dueño fue de excelencia, junto a su esposa e hijas maravillosas. Gracias.

No encuentro nada que me disgustara. Podría buscar alguna queja, pero no tengo nada de que quejarme. Y por último, quisiera haber tenido más tiempo de estadía, ya que teníamos que regresar, eso fue lo peor.
