Kedin's II is between Poppies I and Poppies II, so it's in the heart of Kuta but still very quiet at night (Unless there is a party going on in the next room). Kuta Beach can be reached in 10-15 min walk.
I stayed there 3 nights in September 2012, met lots of nice people (some of them living there for 1 month or more).
The room was more or less clean, bed comfortable, lots of storage space, fan was working fine, bathroom (with cold water only) had a shower and western toilet. The included breakfast was tee or coffe with fruit salad or toast and egg or pancake.
I paid 125'000 IDR per night, wifi costs 20'000 a day (only available in lobby). Staff was friendly enough. They don't take reservations and are usually fully booked, your best chance is to walk in between 9 am and 11 am when people are checking out.
Overall, the place is worth the money if you want to party in Kuta but still enjoy some relaxing time at the nice pool and are on a low budget.More
