This hotel is beautiful and the signature scent when you enter it is divine. Lovely amenities. It is close to great shopping and restaurants. Thanks to Karin Gomez in the Executive Offices who had great suggestions of things to do. Much appreciated. Will definitely return. Elizabeth & Briana

"Special thank you to Chef Fermin!"

10.0

I would like to leave a 5 star review for Chef Fermin. I stayed at the JW Marriott for a business trip March 21-23. I had breakfast at the hotel on Saturday and Sunday morning. The breakfast menu had no options for vegans. Chef Fermin came out to speak with me, and then proceeded to make an AMAZING breakfast of stir-fried tofu with broccolini and kale leaves, with side of potatoes sauteed with onions and bell peppers. The dish was perfectly seasoned! It was absolutely delicious...that I asked for the exact same dish again on Sunday. I want to thank Chef Fermin for his creativity, excellence, and most importantly, taking the time to listen to my needs. Chef Fermin made my experience at JW Marriott memorable. Thank you Chef Fermin! As a side note to JW Marriott, please make a vegan option standard on your menus.
