I'll be honest: I almost gave Mountain Top 'just' four stars. Why? When we booked, we were offered two rooms: one with a bigger bed, or one with a smaller bed but with a view. We chose the latter, but were given the former. It turns out the room without the view doesn't have a window (or rather it does, but only an internal one that over looks the hot tub - which can be used by other guests). This meant it was both dark and not ever so private.
However: the hospitality of the owners, their knowledge of the area, the hot tub, the wine in the evening and the breakfasts (oh, the breakfasts!) made up for the room. It really did. I can honestly say the two breakfasts we had here were the best of our two weeks in California.
Additionally, the location is really interesting. It's not in Sequoia National Park, so it's a lot quieter. There's still plenty to see and do, and we often felt like we were on our own. We stayed for several hours on Dome Rock enjoying the sunset, for example, and didn't see anyone else all the time we were there (incidentally, you should go here - it's like being on top of the world).
All in all, it felt like a place which you could really explore - a lot more 'untouched' than the main tourist places in Sequoia National Park or Yosemite.
It's worth noting the village it's in is very small, and only has one restaurant-cum-cafe that's not open late. On the day we arrived, it had already closed. Luckily, I had spoken to Mountain Top on the day and they'd warned us - so we picked up some sandwiches in the previous town.
If you want to stay in the area, there's not much choice unless you camp. So we were grateful that Mountain Top was so homely and friendly. But if I went again, I'd make sure I got the other room!
