They were so accommodating my husband had had medical issues before we left on our trip and Dhati made sure we got our room a little early so my husband could sleep! Beds were comfy shower was big and it was a great location.
This hotel was easy to get to with friendly staff. We had a room right above the trolley line and took a ride all the way to the ocean front. Very nice place.
We enjoyed our stay at the Axiom and this room was perfect for our family. The location could not be beat! The room was clean and well appointed just as the photos show. The staff and cafe/bar downstairs were a huge plus! 10/10 recommend!
