tldr: If you want a smooth trip, I highly recommend avoiding all Heirloom properties! I recommend reading this whole review before booking.
When I checked in, there was a box fan running in the kitchen and the place was extremely hot. 80+ degrees and increasing. The AC did not work, and it was very clear that they knew about it (why else would they have a fan running?). After several hours of a back and forth, and an attempt from a maintainance person to fix it, they had an open unit with the exact layout right next door that they moved us to. I have no idea why they didn't offer that up sooner. For the inconvenience and after a couple phone calls, they felt $75 was enough to make it right and claimed they didn't know there was any issue in advance.
The second unit (no box fan in this one!) was a bit better (and cooler), but the fridge/freezer was not working properly and did not make ice until the second day after they came to fix it while we were out. We unfortunately had a family dinner catered, and had to throw away leftover food from the first night.
We did not feel safe in the area the unit is in. It is with a collection of new builds surrounded by houses that are not so nice. I know that the host has responded to some other reviews saying this isn't true, but we witnessed one of the neighbors showing off their gun collection to friends in their front yard in the middle of the day, while their young children used the porch as a restroom.
As for parking, you are told the morning of that their is 1 offstreet spot available and they otherwise recommend parking in a garage 10+ minutes away. They tell you not to park on the street even though there is no signage telling you not to, but we did get a complaint from a neighbor saying that we could not park on the street.
The pictures of the unit are also a bit deceiving. Some of the rooms are photographed to look bigger than they actually are. Also, there is no mention of the amount of stairs. There is a long flight of stairs to go up right when you enter to get to the main family room, and more stairs above that. I was there with my elderly parents and sister with a disability, so a heads up about this in the listing would have been nice.
Overall, I guess you get what you pay for. The value here seemed good, and the place is newer and overall clean, but the fact that both places had issues makes me think that this host is one you will want to avoid. But hey, I guess if there's problems, and you have to haul all of your stuff up/down multiple flights of stairs in 80+ degree heat and put a pause on the start of your vacation, you'll at least get a 3% refund!
