I stayed in the rooftop tent and had a great experience.
As you can tell from the pictures, their entire house is filled with cool funky decor. Views and sunsets are amazing, it's quiet on the roof both in terms of the rest of the house and in terms of surround neighbors and streets (good thing as I'm a light sleeper) But I slept great in the comfy bed and with lots of fresh air.
I regret that I was out late most evenings and didn't get to see more sunsets or connect more with these sweet hosts!
