Loved our "glass room" as it had a rustic charm with beautiful windows overlooking a pool and garden. Very surrene. Clean room and loved the semi outdoor shower bathroom.
The man who let us in left us with our key when we arrived and we didn't speak with him until we left.
The only down side we had is that we are backpackers and the walk to the closest transit station was 15-20 minutes. We took a cab back one night and the cab driver didn't know how to get there. Another 20 min walk away however was a great neighbourhood filled with restaurants. If you are okay with the walk then it is no problem!
Otherwise, I would definitely recommend as it is an oasis in the heart of KL.
