Hi Bridget,
I understand your concern and agree that you are providing a very high standard service, for what you explain. My suggestion would be: communication, communication and more communication.
I live in an under-rated area in London, in zone 4 and my big concern is that guests will give me only few stars for this.
The way I have been avoiding it is by telling them what to expect during the messages previous to the booking, i.e. distance, travelling times, prices, safety (happy to say it is a safe area), amenities or lack of amenities, so they do not find it as a surprise because not everyone reads all the rules and descriptions before making their choice.
Once they have made their decision and are here, I make them notice how quiet the area is and how fast we get to the center even though this is a big city and how interesting to be in a multicultural place. I think it helps making them notice the pros and the cons and underline the positive side of it.
I still get four stars amongst the 5´s but in the reviews guests point out what I have been making them aware of!
Perhaps if you help your guests to take the responsibility for their own decision on the small incovenience your listing my have, they will put that aside and be ready to appreciate more the wonderful hosting you are giving them!
It might be more work and time consuming, but might be worth the effort.
Good luck!
