Jonas was pleasant and communicative both before arrival and when we met in person on arrival. The apartment was clean, spacious, with great balcony and had everything someone might need while staying for a city break. Great amenities are within walking distance, and the metro from the airport can be walked in 5 minutes.
Jonas was also quick to respond when it seemed like there was some issues with the WiFi (not the host's fault, provider outage).
The only possible criticism I could offer is that the sofa bed in the living room is actually just a big sofa, but absolutely a comfortable place to sleep!
