Katarina is a perfect host. I opted for the airport pick up and she was welcoming and had lots of advice. She also picked me up for a very early flight and I really appreciated that. I would recommend the airport pick up because it's a reasonable cost and the apt. may be a bit difficult to find on your own.
The apt. itself was spotless and the view from the balcony was perfect. I was using the apt. as a remote office for a week and it was comfortable (wifi was fast and reliable) but there is no a/c. This was fine as the weather was 26-28 all week and there was a fan but I could see it being uncomfortable in the apt. if it were hotter.
However, there is a downside: the smell emanating from the pipes. It was much worse than my expectations from the other reviews. It ranged from moderately bad to awful and never fully went away. Closing the bathroom door would prevent the smell in the rest of the apt. but it meant that the bathroom was uninhabitable without plugging my nose - so not ideal.
I know that the hosts have tried to deal with it but whatever they have done is not enough.
I wouldn't hesitate to recommend the apt. if the smell issue is resolved.
