We had a nice and comfortable stay at Aron's place, though this place isn't for everyone, which I will outline below.
But first, the good stuff. Aron is a great host super nice and responsive. The place is kid-friendly, we had our two kids with us (5 and 7) and they were thrilled to find a shelf full of books and toys. The kitchen is modern and has all the basics. I was able to make pancakes and oatmeal for kids in the morning - there was salt, frying oil, sugar, honey, and all needed utensils.
The bed was comfortable and the water pressure was good. And everything was clean.
However, if you're tall or claustrophobic, this place is not for you. Aron does mention a couple of times in the description that the ceilings are low, so do not disregard that. I am 5.7 and my husband is about 5.8 and this is probably the tallest you can be to safely pass without having to bend your neck or bumping into the ceiling in some places, though it's not as low everywhere.
Another thing, there are almost no windows. There are a couple of tiny windows with curtains, but they don't really count. There are a couple of mirrors in the living room which helps a bit and it was a great solution on Aron's part, but I know some people must have windows, so just be aware. We didn't have a problem with that, but we have a friend who cannot be in a room w.o. windows.
And finally, if you're sensitive to noise, bring earplugs or headphones. If there are people upstairs you can hear them walking really well and you're right next to a basketball court, so you can hear the kids playing. But we're also a bit spoiled because we usually live in a house in the woods, where there is no noise other than birds. If you're used to an urban setting that probably won't be an issue.
All in all, the place is nice, just be aware of those couple things.
