I see. Thank you for clarifying this for me, Irina.
Since there is likely to be a legal challenge to your actions based on the past conduct of this company, it is very important to document any communications you have with the company as well as any incidents, such as what you have described above.
It sounds as though the company has engaged in fraud since they misrepresented the property to you and prevented you from viewing the property where you would actually live until it was too late to back out of the agreement.
Under CA law, they also have a duty to make necessary repairs which it appears they have failed to do. Your remedies for that include filing a complaint with the local building inspector since they have the authority to inspect and compel the owner to make necessary repairs, you can also repair and deduct the cost of the repair from your rent under certain circumstances, and you can even move out of the rental property and sue for damages
if the failure to repair affects the health and safety of the tenants.
Here is a link which provides more information on the repair and deduct remedy as well as the ability to abandon the property where it is uninhabitable:
You can sue the landlord for fraud as well as other damages depending on the remedy you choose in small claims court, seeking damages you have sustained as a result of their fraudulent conduct as well as their failure to make necessary repairs. But it is critical that you have documentation, including writings, journals, photos, witnesses, and any other evidence you can gather to prove your allegations so they are not able to defeat your claims.
