accommodation request

[MK22]

Is the letter below grammatically correct?

Dear Dr. j...,

Alpha Center contacted to me and I sent for them some documents, but for accommodation in Londen having a problem, my friends suggested to me that submit my request on Facebook groups for finding a suitable room and I have done it some days ago. However, I cannot find any room, yet. On the other hand, I should write my accommodation address in London for the Alpha Center’s forms.

Would you mind helping me with finding a room?

Best wishes,
M...

If the organization's name is Alpha Center, you have to capitalize it each time. If it's a British organization I would expect it to be Alpha Centre.

OK, I did it. Alpha Center is an imaginary non-UK center.

OK, I did it. Alpha Center is an imaginary non-UK center.

You have to capitalize all the main words of a proper noun.

Is it ok, now?

The sentence is too long and muddled-up. It is too much for the first sentence of a letter. It is like you expect a reader to have some prior knowledge of what you are talking about.
What is the purpose of your letter? What did Alpha Centre contact you for? What documents did you send them? What do you mean by "accomodation n London having a problem". It is like expecting the reader to read your mind.

See my corrections above.

On a practical note, don't look for accommodation on Facebook. It's full of scams! You should look on reputable accommodation agency websites.
