Just stayed there for a week in early July. We were in the furthest north condo (Buddy Dive directly across the fence from us). Can't speak for the convenience of other Sand Dollar condos, but F21 was ideal. Set up for divers, by divers. A few yards to an entrance to the north end of Bari Reef (or south end of Buddy Reef). Convenient location. On-site dive operation (Dive Friends) suited our needs in every way. On-site restaurant (Eddy's) was good for a few meals - we found it to be better than the bar at Buddy's. Staff at the front desk were very friendly and helpful. We had 6 in our group, so the 3 BR condo was ideal. They do rent it out as a 2 BR condo as well. All good - no complaints at all. As a frame of reference, I've been to Bonaire 3 times in the past - Hotel Bonaire (dates me, I know - 1981), Bonaire Oceanfront Apts (near downtown - 2009), and Buddy Dive (2012). This was my best overall experience in Bonaire.
