My stay at Ivo's apartment was very pleasant ! First, Ivo was very welcoming, he prepared the bedroom very nicely, with chocolates, and a document written very precisely about directions and tips about Zürich.
I had my private bedroom and bathroom in Ivo's apartment, and everything was very clean. Also, Ivo's apartment is very beautiful, big, has a rooftop, well... it's kind of a dream to live in such an apartment !
Location is very convenient ! Right next to the central train station (5 min walk). As opposite to many other cities, the area around the central train station in Zürich felt very safe and nice. Also, it's a 15 minute walk to the old center of Zürich.

Overall, I'm very happy that Ivo's place was available for these two nights ! And thank you Ivo !
