We had a great stay and the house is in good shape inside.
Note that we found that the layout of bedrooms vs bathrooms was not ideal for our party (2 families with 2 adults and 2 children each; some of the children were only 3 and younger). The two bathrooms are on the ground floor, but the largest bed room is on the top floor with a very steep stair case down. Unfortunately one of us slipped and fell down the last few steps during the night while trying to take one of the little kids to the bathroom. There's nothing wrong with the house, just a result of the layout.
Also note that the bathrooms a quite small - fine for one person, but tricky if you don't have time to fully "serialize" the bathroom routine with so many people as we had.
The only thing I'd recommend to the owner is to take care of some of the decay on the siding of the house before it becomes a problem (I've just been through that with my own house).
