My wife, daughter and I stayed at the "On Island Time" condo the week before July 4th. The condo was very nice, roomy and most importantly extremely clean (probably the cleanest VRBO we've ever stay in).
All the furniture was nice and the decor was enough to give the vacation condo vibe, without being "too much" and nothing I had to worry about my daughter messing with or breaking, which is nice.
The apartment doesn't have AC, but it has plenty of fans and windows on all sides, so it is pretty easy to cool off. Bedding, furniture, bathroom were all nice and in good condition. The full size washer and dryer were very nice to have after a week of hiking.
We cooked a couple of times and found the kitchen was pretty well stocked with the needed cookware, but has basically no storage containers, so beware if you plan on having leftovers. The range was pretty anemic, much less powerful than my electric range at home and a few more ice trays would've been nice.
The owners always responded to me very quickly before I checked in. I had no need to contact them after I arrived.
Southwest Harbor is a pretty sleepy town, but this condo has the best location within town I could imagine. Easy walk to everything, and I had no noise issues. I was able to walk across the street to watch the July 4th fireworks. Also, very easy and spacious parking right in front of the door.
I would book this condo again in a heartbeat.
