I've narrowed down to these two for next August. Great TA reviews for both. Same price for both.
I think Tania might be more central and looks lovely -- it's managed by Serene Villas but location is separate. www.balitania.com
Nyaman is brand new and looks lovely. Especially the 4 bedroom which is out of our budget, but 2 bedroom nice too. http://nyamanvillasbali.fr/design/?lang=en
We are a family of 4 (kids 8 & 10). We stayed in Saba Villas last summer -- loved it but want something right in Seminyak this time.
If anyone has seen these or stayed here, I'd love any input.
