Betty is very nice and welcoming and her home is nice. I stayed for two weeks in late June 2018. Unfortunately, when I woke up the first morning, there were swarms of ants all over all of my things. Like hundreds. This was the first place I was staying after moving across country, so I had all of my things in the room and there were ants everywhere. Betty seemed surprised, but helped spray repellent in the room. I ended up buying my own ant traps and raid spray to keep them at bay. It was an ongoing problem in the room and the bathroom the rest of the trip, but never as bad as this first day Be careful what you leave out: toothpaste, mouthwash, lotions could attract them.
Other than the ants, the stay wasn't so bad. The room is spacious and quiet, there's a porch you can sit on and the bed is comfortable. The room does also get quite hot though, especially at night.
A few things of note: When I booked, the listing didn't say this, but Betty requests a $25 key deposit when you show up. It's refundable, but it caught me off guard. Also, it's about $3 to do a load of laundry, in quarters. I didn't expect a house to have you pay for w/d, but she has made it so. The lack of kitchen use is difficult for a long term tenant.
Overall, it's a fine place to stay, but it should cost less and you should expect to have to deal with ants.
