In your case, you should fill in Section 32 of the visa application form as follows:

Cost of traveling and living during the applicant’s stay is covered by: - Select “by the applicant himself/herself.”

Accommodation provided: - Since you will be staying with your friend but they are not financially sponsoring your visit, you should still indicate that accommodation is provided. - You can check the Accommodation provided box and clarify that it is by a host (your friend), without any financial sponsorship.

It’s important to provide clear information to avoid any confusion. You might also want to include a cover letter explaining that your friend will be providing accommodation but not financial support for other expenses. This way, the consular officers will have a complete understanding of your situation.
