The living room and master bedroom shades have wear and tear. They did not work properly in room 320. Shades are broken. Lost about 2 hours of my vacation repairing and putting Shades back.

From check-in to check-out, everyone was helpful and efficient. Ricardo provided us with all the information we needed and showed us around the hotel. The tiki bar at the entrance to the beach was a great perk. Resort was clean, room was spacious and bed comfortable. Chase greeted us at the beach each morning and set us up with chairs, umbrella and towels. We also enjoyed the pool; very comfortable pool chairs. All around great experience at Amrit. Will definitely return.
