As a Travel RN, it is super important for me to stay in a safe, and clean hotel while I look for my permanent housing while on assignment. This hotel is darling. The rooms are super spacious, and the bed is so comfortable you do not want to get up for work. The rooms, and hotel are extremely clean, and decorated so lovely. The check in is completed virtually, and so easy. The young lady was professional, kind, and extremely helpful. There is an elevator close to the lobby to take you to your room. This hotel is located in a super safe area of Glendale, CA. It is walkable to many restaurants, coffee shops, and one of my favorite bakeries Red Ribbon. I highly recommend this hotel everyone.

Hotel itself is clean. There was a fresh paint and sometime a strong chemical smell in the room. I was ready to find a new hotel if I could have canceled this stay. There is no coffee pot in the room, not very much space to set anything out, few drawers to put anything away. There is a coffee and flavored water machine in the lobby. The coffee is very bland, much like drinking flavor water. Overall, it’s all in the photos you just need to look closely. The room is spacious, beds are comfortable. It appears the hotel was just renovated. By the area it is located, it was most likely a pay by the hour motel in the past. At least it was clean.
