Great ideas. I sometimes take guests from the station to our accommodation. Especially when the guests are a little bit older that is very much appreciated. And the little things in the room help a lot. I do not charge for those things, but I can imagine that if you have a possibility to order extra services, that you can charge for that. You could always post pictures with your accommodation showing your extra services... through booking you can start a conversation with your guest as well offering extra services..
