Re: Sunstone Hotel Investors, Inc.

To the addressee set forth above:

We have acted as special tax counsel to Sunstone Hotel Investors, Inc., a Maryland corporation (the “Company”), in connection with its filing of (i) a registration statement on Form S-3 dated February 24, 2023 (together with the documents incorporated by reference therein, the “Registration Statement”) and (ii) a prospectus dated February 24, 2023 (the “Prospectus”), in each case, as filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Act”).

You have requested our opinion concerning certain of the federal income tax considerations relating to the Company, including with respect to its election to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Code”). This opinion is based on various facts and assumptions concerning the business, assets and governing documents of the Company, Sunstone Hotel Partnership, LLC (the “Operating Partnership”), and their subsidiaries, including the facts set forth in the Registration Statement and the Prospectus. We have also been furnished with, and with your consent have relied upon, certain representations made by the Company, the Operating Partnership and their subsidiaries with respect to certain factual matters through a certificate of an officer of the Company, dated as of the date hereof (the “Officer’s Certificate”).

In our capacity as special tax counsel to the Company, we have made such legal and factual examinations and inquiries, including an examination of originals or copies certified or otherwise identified to our satisfaction of such documents, corporate records and other instruments as we have deemed necessary or appropriate for purposes of this opinion. For the purposes of our opinion, we have not made an independent investigation or audit of the facts set forth in the above referenced documents or in the Officer’s Certificate. In addition, in rendering this opinion we have assumed the truth and accuracy of all representations and statements made to us which are qualified as to knowledge or belief, without regard to such qualification. In our examination, we have assumed the authenticity of all documents submitted to us as originals, the genuineness of all signatures thereon, the legal capacity of natural persons executing such documents and the conformity to authentic original documents of all documents submitted to us as copies.

We are opining herein only with respect to the federal income tax laws of the United States, and we express no opinion with respect to the applicability thereto, or the effect thereon, of other federal laws, the laws of any state or other jurisdiction or as to any matters of municipal law or the laws of any other local agencies within any state.

Based on such facts, assumptions and representations, it is our opinion that:

1. Commencing with its taxable year ending December 31, 2004, the Company has been organized and has operated in conformity with the requirements for qualification as a REIT under the Code, and its proposed method of operation will enable it to continue to meet the requirements for qualification and taxation as a REIT under the Code; and

2. The statements in the Prospectus under the heading “U.S. Federal Income Tax Considerations,” insofar as such statements purport to constitute summaries of United States federal income tax law and regulations or legal conclusions with respect thereto, constitute accurate summaries of the matters described therein in all material respects.

No opinion is expressed as to any matter not discussed herein.

This opinion is rendered to you as of the date of this letter, and we undertake no obligation to update this opinion subsequent to the date hereof. This opinion is based on various statutory provisions, regulations promulgated thereunder and interpretations thereof by the Internal Revenue Service and the courts having jurisdiction over such matters, all of which are subject to change either prospectively or retroactively. Any such change may affect the conclusions stated herein. Also, any variation or difference in the facts from those set forth in the Registration Statement, the Prospectus or the Officer’s Certificate may affect the conclusions stated herein. As described in the Prospectus, the Company’s qualification and taxation as a REIT depend upon the Company’s ability to meet the various qualification tests imposed under the Code, including through actual annual operating results, asset composition, distribution levels and diversity of stock ownership, the results of which have not been and will not be reviewed by Latham & Watkins LLP. Accordingly, no assurance can be given that the actual results of the Company’s operation for any particular taxable year will satisfy such requirements. In addition, the opinion set forth above does not foreclose the possibility that the Company may have to pay a deficiency dividend, or an excise or penalty tax, which could be significant in amount, in order to maintain its REIT qualification.

This opinion is rendered only to you and is solely for your benefit in connection with the transaction described above. This opinion may not be relied upon by you for any other purpose, or furnished to, quoted to, or relied upon by any other person, firm or other entity for any purpose, without our prior written consent, which may be granted or withheld in our discretion, except that this opinion may be relied upon by persons entitled to rely on it pursuant to applicable provisions of federal securities law.
