My wife and I stayed at Jungle Villa for three nights in September and truly enjoyed ourselves. Our trip to Bali had various legs, starting up North, then Ubud (jungle villa), followed by Nusa Dua. The Jungle villa was our "roughing it," but honestly, it was nothing of the sort.
The villa is located in a secluded area that is a mixture of locals and other villas. It is about a 5 minute walk from the main road, but that walk is quite nice, seeing local places and plenty of quiet (and good) restaurants.
I read some comments that it's difficult to access with your bags, but the villa was extremely helpful, sending staff to meet us at the main road and help us with everything - they were quick and very helpful.
To walk into Ubud, it takes about 20-25 minutes, but there is a sidewalk for the full trip. Lots to do and see in the area. Within 5 minutes of the villa there is tour pick-up, scooter rental, taxi service, massage, restaurants, and a few local shops. You really have everything you need close by.
Do be prepared for some company in the outdoor bathroom. For us, it wasn't anything bad, just some lizzards, but they're more scared of us than us them. The villa is very quiet and peaceful.
The included breakfast is situated nicely in the garden, though does have limited options.
Overall staff, location, service, was great. And the pool is as beautiful as the pictures make it look!
