This is my first post in this Forum and I specifically signed up for this. I hope this does not violate the posting rules, I just felt the need to let you know.
In the past I rented an apartment from Vivo35 AG in Winterthur. They may have a cool concept, but they have at least two serious flaws. And it seems like they seem to be targeting people who need an apartment fast, largely from abroad... So the issues are the following:
They will ask you to submit a rent deposit to their private account . This is explicitly forbidden by law ( OR Art. 257e ). This puts YOUR money at risk, because the can now freely handle it. And if they go broke whith whatever business they are doing, your money is gone.
When you ask them about it, they will explain: "We treat the deposit seperate from our other accounting. But we offer our Customers to open u a rental deposit account and we will transfer the deposit to it." So: First they try to get your money, and if caught, you can do all the paperwork for opening of the proper and legal rental deposit account yourself.
They have a key-badge system in place for the apartment doors, which allows them general access to ALL apartments . Altough there is not an explicit law against this, there have been rulings that forbid this practice (based on OR Art. 257h ).
Worst of all, they even just blatantly use it! While viewing and apartement which was advertised for rent, we just spontanously popped into another appartement, where all sorts of private things of the tenant where standing around. There was no possibility that he or she could have known that people come to view his appartment (which was not even posted up for renting...).
And of course, anyone with the key (the 2 owners, the cleaning lady, and maybe more) can potentially mug your stuff. And neither you or them can then proof or disproof who it could have been.
When confronted with the fact that this is illegal, they aggressively answered with the usual "We are still the owners of this house, it is our right!".
So, if you wanna rent an apartment there (after all, they are located pretty well), just be aware of these circumstances. I highly recommend not to, they are also way too expensive.
