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.

This was a nice enough stay overall, but a lot different than what I was expecting. First, there was a discrepancy in what room type Orbitz portrayed as being booked and what was actually booked. I booked a Premium King room through Orbitz; this apparently did not actually mean a Premium King as described on the hotel's website, but rather a studio king room which is more in-line with the Classic King (but also not because the hotel attendant said it's the Classic King room which is larger and comes with a separated dining area). Upon bringing it to the hotel staff's attention a few days into my stay, I was informed this was a 3rd-party booking site problem and basically that was that. Would that have ultimately made a difference in the other quirky aspects of my stay? Maybe, maybe not. The property has been through a lot since its inception, despite its renovations (read: paint and fixtures). There were several issues with the main entry door, bathroom door, and large window in our room, primarily w/ incomplete closure and weather-stripping. The bathroom door was wonky such that it couldn't close all the way and if you forced it, you're likely to be stuck. Lack of good exterior door/window seal allowed worms into the unit every evening! Did NOT enjoy that whatsoever, and no towels against the door could stop them. TP and towels were very thin, breakfast was OK. Bad industrial smells in courtyard some days. Restaurant next door can be very loud on weekends at close.
