This is definitely a very cool apartment. It's worth mentioning however it hits home that this place is someone's day to day apartment. There's lots of "stuff" here. Not that it's a negative aspect to the apartment at all. We enjoyed the vibe of it.
Excellent penthouse patio. We had some fantastic breakfasts in the sun here.
Great location for getting into any area of the city. Decent connection for buses and metro stations.
Comfortable bed and quiet neighbours.
The owner is easy to communicate with and she showed us a lot of flexibility when we had some technical issues ordering through ABB.
The organic/hipster'esque eclectic feel of the apartment make you very relaxed.

Slightly warm and not the best ventilation, so in 25 degrees plus days it can get hot.
Some traffic noise/ drunk people when you open the window to the bedroom. But this is a European capital and a central apartment, so goes with the territory.
No TV, but there's a boombox for playing music.
The owner is clearly into the vegan/organic life, and this is largely cool, but I would as a future guest buy my own toilet paper at arrival, because the stuff she provides you isn't very practical. It's the type of organic paper that very easily clogs the toilet.
There were minor issues with the degree of cleaning in the bathroom, kitchen and a livingroom table full of broken glass, which isn't acceptable (to us anyway), but this is easily handled and I suspect the owner will act on that for the future.
I'd easily visit this apartment again due to the very hip vibe, fantastic patio
