Our family of five (parents + three kids) stayed four nights at Villa Balissima.
The villa is lovely and spacious, but it needs a bit of maintenance (the pool was cloudy, and the cistern in the master bedroom had a dodgy float valve so the toilet wasn't refilling after a flush). The bi-fold doors on the master bedroom are also very heavy (my wife couldn't open the doors). Sliding doors would be better.
However, our main issue was the location, just off Jalan Kerobokan which is a very busy road. It is a 20 minute walk to Seminyak Square.
We also thought the rate was high compared to similar accommodation in Seminyak, especially as the rate didn't include breakfast.
However, if you are looking for a spacious villa and plan to rent a scooter, or don't mind some walking the villa is OK.
