La amabilidad del personal.

Que corten el servicio de pileta, por el mundial. Soy empleado y jamás deje de trabajar. Quise estar en la pileta por que lo necesitaba.

La atención excelente, la chica de limpieza y la atención en general

El restorán, muchas demora pero la atención de los meseros es muy buena

Lindo lugar al cual volvería.

Buena ubicación, la habitación amplia, el personal muy atento y cordial.

Si bien la habitación era linda, que no cuenten con Smart TV en 2026 siendo un hotel 4 estrellas me parece malo. La cochera $30.000 diarios es cara. No hay room service y la carta de comida es acotada.
