  • Alex Pirtle review score of 5 out of 5

    I was nervous about there not being a concierge, but it turned out to not be a problem! I did have questions that were answered very quickly through the chat system. The room and bathroom was great, and the design of the room and hotel bar was very cute. We loved having a balcony to step out on. I would definitely stay here again.
