Unimpressive hotel, and my dress mysteriously disappeared
Until I accidentally left my expensive dress in my room's closet (and called them within a few hours of checking out to let them know of my error and arrange pick-up) and the hotel claimed no knowledge of it, I was planning to give the Copley Square Hotel three stars, for being an unremarkable hotel. However, it has since made itself remarkable by losing my dress and has demoted itself to one star - I'm really quite furious about it, and it brings into doubt the honesty of the staff. I would certainly hesitate to stay here ever again due to security concerns about the belongings I leave in my room. 
Prior to this incident, the hotel was fine. Great location, and a stylish lobby (with free coffee in the morning, juice in the afternoon, and wine in the early evening) only pave the way to disappointment at the rather small, dated rooms, which have a completely different style to the lobby. We were apparently 'upgraded' to a queen room, but our room was pretty small, and the bathroom was ridiculously small. For example, I'm not fat, but whenever I sat on the toilet, the toilet roll holder was so close it dug into my thigh. You couldn't really put anything on the wash basin. 
But at the end of the day, you need to be able to trust hotel staff. I definitely left my dress in the closet, I alerted them within hours, and they claim they don't have it. I'd not advise staying here.
