9/10 Wonderful! (860 reviews)
Room a bit small, really no area for luggage, bathroom door squeaked loudly, the sink drained very slowly, loud group outside in the common area until 2 am totally clueless that there may be guests trying to sleep and had to call front desk who were 10 ft away from them to ask them to quiet down then additional people did the same a while later. Overall hotel was fine but would not stay again, many other nice hotels to choose from .
