Nicely tucked off in the narrow streets, with easy and quick access to clothing shops, restaurants and bars. It is a 5 minute walk from the ferry terminal and provides you with a clean and friendly environment to rest your head.

Probably the best hotel we’ve ever stayed in. I was a little bummed because their spa and restaurant was closed but their staff went above and beyond to make sure we were comfortable. The breakfast was the best food we had while island hopping too.

The staff and the spa were amazing and I will definitely be back. Such a cool property and the location was perfect, walkable from the port and right in the middle of where you want to be. Steps to the best restaurants and nightlife we couldn’t have asked for a better hotel to stay out. Loved everything about it! The prestige suite is amazing!
