Not "bright", average daylight at best. They're trying to do a good job but the architecture is a swing-and-a-miss for me. The windows are few and small, and all on one side of the building so there is no ability to create a cross-breeze. Since it is also close in with other structures (not only the main house but a shed, the neighbor's house, etc.), it does not get good daylight inside.
It cannot comfortably sleep 4: The downstairs bedroom is completely dark and windowless (there is some glass on the interior wall but it is ineffective), and the upstairs bed has so little headroom that it is impractical to sleep two there — even with one, you are going to hit your head, elbows, and knees in the course of trying to sleep. (I am used to tiny ultralight backpacking tents and this bed is much more cramped than those.)
Let me pause and mention the good parts:
* The front porch gets sunlight throughout much of the day and this is a nice place to sit or work — for me, the one redeeming part of this Airbnb.
* There is no traffic noise, as it's midway between the two nearest arterials.
* The hosts were gracious and communicated well.
* The hosts are aiming for nice aesthetics, for instance with wood trim and nice built-in shelving.
* Good wi-fi.
I would not book again, however, unless options were extremely limited.
The furniture needs a rethink as the living/dining area is very cramped — a rearrangement and swapping out some pieces would save this part. Between this and the extremely cluttered yard, it's difficult to do any yoga or stretching — there isn't anywhere you can lie down and extend your arms.
The kitchen equipment is about average. The sponges were old and smelly. (I don't just mean they weren't brand new, I mean they hadn't been replaced in months. No replacements were provided.)
The location broadly speaking is great, but it abuts a park and elementary school, so there is fairly constant noise (although it is cheerful). Not the place for those seeking quiet, though. You do sometimes get drunk or high teenagers in the park late at night.
The driveway is extremely challenging. I have parked in old cities of Europe and the Maghreb and yet had a very hard time fitting my non-truck non-SUV passenger car between the two low brick walls. If there are cars street-parked around and opposite the driveway then it may be nigh impossible to get in.
