We had a lovely time at Bertha and Kazu's place! While we didn't meet them directly, we had wonderful communication through both the app and Bertha's sister (who was extremely kind and friendly). They even helped coordinate keys when we had to leave for the airport at 5:30AM!
The home itself was perfect and exactly how it is pictured (maybe a little bigger actually!). Plenty of light, lots of plants, comfy beds, and access to a roof with a view! Good (but higher end) neighborhood with tons of bars and restaurants.
We left very happy with our stay and would absolutely recommend.
