We stayed at Del Mar for three night during our visit to Riung. The owner Itchan and his staff were very friendly and helpful, and helped us with everything we needed including laundry, trip to the 17 islands, scooter rental and driver to the airport when leaving. The rooms are big with good beds, a functional bathroom, and air conditioning. The nice garden setting is another plus, and the food is good (although the first day was better than the second). The only downside may be that everything may be somewhat expensive for what is offered compared to other places we visited in Flores, but this may be because of limited competition in Riung which is not very touristy.
