So, having seen an suggestion by u/aartifex, I will give a try to find a potential flatmate(s) here.

If there is anyone who wishes to start flatsharing from this summer and is interested in doing so with me, please DM me. A short introduction of me is given at the end. However, I have not yet had any rental contract, so we may need to find a dwelling together.

• I am a science PhD student at ETH. I am male and Asian.
• My monthly budget for flatsharing is 1500 CHF.
• I prefer to live near ETH Hönggerberg with max. two other ETH/UZH students.
• I like to occasionally have some activities together with my flatmates (cooking, movie, sports, excursion, games, study etc.) rather than we share a flat just to reduce our living cost.
• The number of overnight guest's staying per week should be restricted by agreement.

I hope to hear from somebody soon!
