Place was as described. When I arrived Sevi was in the middle of cleaning up after a flooding in the basement so he was understandably busy but he was very helpful and available as was his flatmate at the time. The neighborhood is very busy but I had no problems with noise. The windows kept a lot of the sound out so I slept well on Sevi's newly bought bed and linens.
It was very easy to get everywhere as the main Zurich station is only 10 mins away while buses were running steps away from the flat. I had a great time in Switzerland and this is a prime location!
