Pros: Very fun theme (we stayed in the Caribbean sea cave), very friendly staff, delicious and somewhat unique breakfast for a hotel, jetted tub in the room was a big plus, themed bed to fit the room. We also loved that there was a log book where previous guests wrote about their experiences in the room.
Cons: The overall condition of the room was a little poor, there were several relatively obvious maintenance issues such as wall mounted fixtures (towel racks, curtain rod, etc..), which seemed to be coming off the wall. I do understand that the age of the building and potentially poor communication between housekeeping and management staff could be a considerable factor.
As a whole, the stay was romantic, unique, and relaxing. And the Logan location is in such a nice calm area, close to several restaurants and activities.
