I had an acceptable overnight stay at the Muthu Newton Hotel in Nairn. It's in a good location and the grounds surrounding it are really nice and well maintained. The staff were friendly and helpful. The public rooms were upmarket and in keeping with a property of this age/period.
The only issues were 1) I was sent an e-mail to do an online check-in. This didn't work and the contact number given was for a hotel in Essex. I tried calling them directly in Nairn (after a search on Google), but got no answer after two or three occasions trying; 2) The food was acceptable, but not great. At dinner, the soup was luke-warm at best. I ordered ice cream for dessert and it arrived in a state of initial melting. I didn't see any croissants for breakfast (only mini muffins) and the sausages were fairly hard.
The room I was in was clean, with fresh sheets and the sort of facilities I would have expected (eg kettle, TV, hotel safe etc). The wifi wasn't great with a speed of 2MBps - OK for web pages and email, but you might struggle with online meetings. Otherwise, the room was quiet and comfortable.
