We stayed in the Lakeview Suite for three nights. We had two adults, a five year old and a baby. Some of the decor has been updated from the pictures shown.
Location: Excellent. 1 block to beautiful beach, go the other way for shopping and restaurants. Can even walk to grocery store (>1mile) if needed. Tiny view of lake Betsy though the windows, best view is from the toilet - not kidding.
Space: good space for two adults plus pack-n-play (provided by Serendipity house) in the bedroom, especially if you block off the internal entry door and just use the external door as we did. May not be so pleasant in the winter. Living space had a sleeper sofa, but it takes up all available room so we used a small inflatable bed (we brought our own) for our 5yo and then propped it in the corner so we had living space during the day. Bathroom is ample, though shower is small.
Amenities: Kitchenette had all appliance, pots, pans, etc. Including dish soap. Need to bring your own salt pepper and other condiments. Bathroom had plenty of towels though some were slightly stained (not gross - just showing wear). No shampoo or shower soaps provided. Enough space and hooks for storage of clothing, gear, and food supplies. Clothesline in back for drying suits was very helpful. We didn't use the picnic table, backyard chairs, or fire pit, but they were all there. "Grill" is a tiny webber charcoal camp grill. Will do the trick if you're desperate, but too fussy for our needs. Peaceful backyard setting with just other home noise, not business noise. Nice front porch to people watch or read. Beach chairs provided in the bedroom. Owner appeared to be working in grounds and doing other maintenance while we were there - I took that as a good sign. Good service interactions.
Cleanliness: Average. This is the one that will keep me from letting my mom stay here. Carpets were worn and had stains and there were stains on the couch. We found earrings in the floor when we arrived which made me question the vacuum job. Linens were clean, but bedcover did not appear to be made of a washable material. Perhaps they switch them out and get them laundered - otherwise... Dust on pictures and flat surfaces, sand in drawers. Looks like they weren't wiped out between guests. Kitchen was clean as was the bathroom. Honestly, I think it just might be too much for one housekeeper to handle during peak season. Nothing gross - just not as nice as it could have been.
We had a great time.
