I recently stayed at Amertha with a friend as we were planning 6 days of diving and we were absolutely blown away when we saw villa #5. It was huge and had more space than the two of us would ever use. It really would be perfect for a small family as there was one master bedroom in the main part of the villa complete with a working desk, daybed, and television/DVD (not that we used this) and its own massive bathroom, indoor and outdoor shower and then the second bedroom also had a big bed and its own bathroom with indoor shower. There are a lot of outdoor areas to hang in at villa #5 including your own pool. The villa also has an outdoor kitchen complete with fridge and utensils but we didn't really use it. of the other hotels closer to the actually building. This villa was about halfway from the beach and road we only heard the mosque very softly which gave it an exotic quality rather than the harsh reality if you were closer to the road or at And it is loud if you are nearby at one of the restaurants further up the road when it goes off 4 times per day.
The spa is pretty good... the treatments I had were wonderful and the setting is simple in an outdoor way but if you are looking for luxury this probably isn't your place; The Madi Hari up the road has a much more luxurious spa. We were more interested in a Balinese experience and felt that this hotel and its spa lived more up to this than the only other 4/5 star equivalent in this area.
The restaurant served a mix of western and Indonesian food and the breakfast each morning that was included was delicious. I had the Indonesian breakfast which was a choice of Nasi goreng or Mie Goreng and both were good. You could also have eggs and pancakes and all came with fruit juice and a fruit plate. The staff were willing and eager to please and every single one of them greeted me each morning, including the ground staff.
Just outside the resort are several warungs where you can have meals and they are all a little different. We went to the one directly across from the Adi Assiri resort and it was so good that we went back 3 nights in a row and even did a cooking class with them. It turns out that it is owned by the manager of Amertha!
Do be aware that there were a few mosquitos when we were here so be sure you shut your doors always and use the netting over your bed.
