As many others before me have said, Irina is an absolutely wonderful host, and a kind and generous person. She was quick to respond to my questions and very flexible and accommodating during my entire stay.
The room is clean and comfortable, and the apartment is very nicely situated, a short (and lovely!) walk from the historic centre and steps away from the tram. Getting to the apartment from the airport while sleep deprived was no issue at all, and Irina provided all the information I needed to make the trip stress-free and easy.
I'll be very happy to stay with Irina again on my next trip to Zurich!
