    A 2-star box nightmare

    Our experience was underwhelming. The building was underwhelming and we did not stay the night, with the expectation that a refund would be fairly considered. The staff was unclear about this procedure and we were told that a manager would review the request in 3 weeks. Simply, don’t expect customer service and be prepared to deal with the reality. Deciding to leave, we found our claim immediately denied through our booking group. It would have been considerate to have known that we feasibly had no opportunity to recoup this expense. This would have helped with our decision making. The true experience, is a damp, confined building desperately needing improvements. Everything listed online is for show, as for the morning breakfast we were told that it was coffee with snacks. That could qualify as continental but advertised is a “very good breakfast” and a wine happy hour. The sole person at the front was not very enthusiastic about this information as we had to ask ourselves about this service, as it’s clearly a false sell point. The room did not have air conditioning, with the only option to fresh air from a window with no screen dumping into an abandoned alley. We are traveling with a child so leaving the window open would have been unsafe. The bedding had stains on it and the hotel generally has seen better days. As said, this was discussed and when asked for a refund we were told they had no control of issuing a refund, and that we would have to work with our booking agent. We facilitated this, but simply this effort was only a gimmick of their to be hospitality. For 260$ on a Wednesday night, you would think the cleanliness and comfort would be suitable. The carpet did not look suitable for crawling, and the mattress with it’s accompanying foam piece was as old as the historic row building.
