A friend and I stayed at Sevi's place for 1 night after returning to Zurich from Lucerne and before we returned to the US.
Sevi's place is within walking distance from Zurich HB, which made both arriving and departing convenient. We stayed at a different place when we were touring Zurich, but Sevi's place seems like a great place for visiting the city as well!
Sevi's place hosts 2 sets of guests sharing the bathroom and kitchen. He furnishes each room with all the necessities, and really shines in hospitality with his outlet converters and local travel guides! His place was a comfortable stay with lots of shared space, and the room is cozy.
As for check in, Sevi offers a timeframe of 6PM-9PM but is flexible upon request. We had a smooth experience checking in ~8:40PM.
Thanks for the amazing stay!
