Puri Manga is the most wondefull place. We loved the garden feel, the pool area (and the view from the pool), the small houses you stay in, the restaurant, the bar and the spa area. There is a clear red line, calmness and authentic style in the overall design of the ressort, which we really liked.
The moment we arrived, we imediatly felt welcome and was greeted with a cold drink and a small wet towel for washing hands and/or face. The staff is very friendly and service minded, even compared to the overall great Bali standard. The food was great, even better then other twice as expensive resorts we stayed at (again compared to the great Bali standard) and the spa area is great. We booked a 5 hours tour with our own driver, which was put together after our wishes (waterfalls, budhist tempel and hot springs), but there are many more places to see, and Puri Manga is a great hub for trips in the nothern part of Bali.
And yes, the last 100 meters up the the resort are a bit steep. But inqurie the resort to send a driver to pick you up, if you cannot find a decent driver yourself :)
It was my second stay at Puri Manga and i will definitely come back again, because it its the most relaxing and beautiful place to stay in Bali, and their staff are the best :)
