We have been hosted at both rooms and whole house. We have enjoyed both. We felt it best if the host asks the guests what they prefer as per entry, greeting, food, etc.
They gave us options. IE. greeting and orientation. Leave us wine and leave us alone. etc.
We felt best cared for when we arrived and there was: a bottle of wine, chunk of cheese, crackers, 2 apples and an insta hot with tea. If you are on the beach = beach towels labeled for beach would be nice.
Offering breakfast was a great option we chose at an additional cost we paid the host directly. It was a big breakfast (nothing hot) but lots of options.
We liked to have a code key entry and a phone check in.
We liked a separate entrance but not necessary.
Hope this helps
Once the host had friends for dinner and that was really awkward as we had to talk through their party. We closed ourselves in our quarters and stayed the night. Felt really strange.
Another checked in - gave us advice and answered questions and left us to be - that was great.
