Needed a procedure done at Cedars Sinai and this Hotel is very close by. The staff is very friendly, parking garage is a little tight, but manageable. Felt very secure, and the complimentary beverages were excellent. Thank you!

PERFECT! This property is immaculate! I think it is the most clean hotel I have ever stayed at- kudos to the housekeeping staff. The attention to detail in cleaning and design couldn't be better. It looks even better than the photos because the energy there is so great! It was fully booked but it felt like it was our own home. Great sun exposure on the pool and the temperature of both the pool and jacuzzi were both perfect. Super comfortable bed and sheets! I loved the setup for the kitchen use and snacks. We didn't want to leave. Thanks to the owner Annick who has created such a relaxing upscale vibe!
