@Therese186 You're off to a great start! Your home is really beautiful, with a lot of character. I like how well the style meshes with the flavor of the region, with tasteful maritime color schemes and thoughtfully chosen vintage furniture. The descriptions are both thorough and concise - easy to read, and just the right of useful information.
And although the home could easily accommodate a group of 4, I think you've made a good choice by setting the limit at 2. That should help keep you off the radar for parties and families and allow you to host within your comfort zone.
It sounds like you've done your research and are already aware of some of the common issues that come up with Entire Home hosting (e.g. parties, smoking). About the latter, you'll eventually get guests who ignore or forget your policy against smoking in the garden; I find that it helps to add some positive language pointing to the nearest place smokers are welcome to light up. That tends to get people's attention.
