I was actually nervous about booking Nonnahus at first, because it seemed too good to be true. But WOW. The pictures are entirely accurate, it's beautiful inside and out. It's easy to get to, easy to find (the host emailed great directions!), easy to get into. It was immaculately clean, the kitchen is very well stocked (We cooked every night, and the kitchen had everything we needed, it even had coffee!) We had a small child with us, and the crib & highchair made our lives so much easier.
The best part was the hot pot- quick and easy to fill, the view of two volcanoes and the river was gorgeous. We actually skipped a few sightseeing things just so we could spend more time soaking.
The beds were comfortable- two of the rooms have bunk beds, and two have double beds. The view out the window of the bedroom at the end of the hall is amazing, try to claim that one for yourself. :-)
The hosts are very easy to work with, very responsive to email, and one stopped by on our first day there to make sure we had gotten settled in. This was an entirely problem-free rental, and I would gladly stay here again!
