We enjoyed our stay at Hotel Diamar. Our room was clean and comfortable, and we were happy to get a sea-facing room. We found the hotel to be very quiet, which was nice. The staff were very friendly. We didn't pay extra for breakfast or dinner, though the buffet menus looked good — more generally we liked eating at the nearby bars and restaurants, which seemed to be frequented by locals. We liked the location on the water and boardwalk. Overall Arrecife feels less touristy than elsewhere on the island, which we liked too. We had a car, and while we would have been terrified to use the (small) parking garage if it were full, it luckily never was and so there was plenty of room to maneuver. We would recommend staying in Arrecife and in this hotel!
