I stayed at Vinh's place for a weekend trip and it was really easy to get to from the airport and train station. The place is about a 30 min walk from old town Zurich or 5 mins to the main train station from the stop down the street. Vinh's airbnb was very clean and the shower was great. Very easy check in, just had to pick the keys up from the Vietnamese restaurant in the lobby of the building. I didn't get the chance to try the restaurant but it was always packed full of people so might be a great option for food nearby! Only downside is the place was pretty basic, just one pillow and blanket for a single guest. Had all the basic necessities for a quick stay when you won't be at the apartment much, but no special touches or a homely feeling. Overall it was a good place to stay!
