I only stayed one night and a couple of more hours at Sevi's but I was very pleased with the experience ! I arrived pretty late (9 pm) and Sevi could not be here right away but I was welcomed by his house mate, Asla, whom was super kind, helpful and made me feel comfortable right away ! Sevi was also very nice, interested and understanding. I was moving in Zürich from France and I was carrying a lot of luggage which Sevi let me store in his apartment for the next day so I was free to do whatever I had to do in town.
The apartment is large, old-fashioned and in the busy/partying part of Zürich, very nice for a week-end !
And thanks for the chocolate !
