We really enjoyed our stay. Overall it was one of the nicest places we've stayed at -- it was nicely furnished (the fireplace was great), thoughtful touches and amenities. Very spacious.
Overall it felt like we were staying in a guest area normally used for friends and family but that we were fortunate enough to also be able to use.
One aspect that we noticed more than perhaps other travelers is quite a bit of noise (footsteps etc) from the rest of the house above. We were working remotely during the day, whereas most guests would likely be out seeing the sights during the day and maybe would not notice as much.
Even with this, we really enjoyed our stay and gave 100% five stars for every category in our review. We felt very lucky to have been able to stay there.
