We had a really great time at Rakhal's apartment. It is perfect when you stay in Zurich with many people (we were 12) and also the location is great. Also Rakhal responded really fast when we had any questions.
The only thing we were a bit unhappy about was the kitchen equipment. The pots and pans were in a bad shape, some things were a bit broken (although still working) and there was barely enough cutlery and glasses/ cups for everyone. But we were also really the maximum amount of people and it still worked out somehow.
We will definitely come back next time we come to Zurich in a group. :)
