Re: Registration Statement on Form S-3

Ladies and Gentlemen:

We have served as Maryland counsel to Host Hotels & Resorts, Inc., a Maryland corporation (the “Company”), in connection with certain matters of Maryland law arising out of the registration of 774,346 shares (the “Shares”) of common stock, par value $.01 per share (the “Common Stock”), of the Company covered by the above-referenced Registration Statement, and all amendments thereto (collectively, the “Registration Statement”), as filed by the Company with the United States Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “1933 Act”). The Shares may be issued from time to time in exchange for units of limited partnership interest (the “Units”) in Host Hotels & Resorts, L.P., a Delaware limited partnership (“Host L.P.”), to the persons referred to in the Registration Statement as the selling stockholders.

In connection with our representation of the Company, and as a basis for the opinion hereinafter set forth, we have examined originals, or copies certified or otherwise identified to our satisfaction, of the following documents (hereinafter collectively referred to as the “Documents”):

1. The Registration Statement and the related form of prospectus included therein, substantially in the form in which they will be transmitted to the Commission under the 1933 Act;

2. The charter of the Company (the “Charter”), certified by the State Department of Assessments and Taxation of Maryland (the “SDAT”);

3. The Bylaws of the Company, certified as of the date hereof by an officer of the Company;

4. The Third Amended and Restated Agreement of Limited Partnership of Host L.P., dated as of February 22, 2007 (the “Partnership Agreement”), entered into by the Company, in its capacity as General Partner, and in its capacity as a Limited Partner, certified as of the date hereof by an officer of the Company;

6. A certificate of the SDAT as to the good standing of the Company, dated as of a recent date;

7. A certificate executed by an officer of the Company, dated as of the date hereof; and

8. Such other documents and matters as we have deemed necessary or appropriate to express the opinion set forth below, subject to the assumptions, limitations and qualifications stated herein.

In expressing the opinion set forth below, we have assumed the following:

1. Each individual executing any of the Documents, whether on behalf of such individual or another person, is legally competent to do so.

2. Each individual executing any of the Documents on behalf of a party (other than the Company) is duly authorized to do so.

Each of the parties (other than the Company) executing any of the Documents has duly and validly executed and delivered each of the Documents to which such party is a signatory, and such party’s obligations set forth therein are legal, valid and binding and are enforceable in accordance with all stated terms.

4. All Documents submitted to us as originals are authentic. The form and content of all Documents submitted to us as unexecuted drafts do not differ in any respect relevant to this opinion from the form and content of such Documents as executed and delivered. All Documents submitted to us as certified or photostatic copies conform to the original documents. All signatures on all such Documents are genuine. All public records reviewed or relied upon by us or on our behalf are true and complete. All representations, warranties, statements and information contained in the Documents are true and complete.

5. Upon the issuance of any of the Shares, the total number of shares of Common Stock issued and outstanding will not exceed the total number of shares of Common Stock that the Company is then authorized to issue under the Charter.

6. The Shares will not be issued or transferred in violation of the restrictions on transfer and ownership of shares of stock of the Company set forth in Article VIII of the Charter.

7. The Units have been duly authorized and validly issued by Host L.P. and will be exchanged for Shares in accordance with the terms and procedures described in the Partnership Agreement.

Based upon the foregoing, and subject to the assumptions, limitations and qualifications stated herein, it is our opinion that:

1. The Company is a corporation duly incorporated and existing under and by virtue of the laws of the State of Maryland and is in good standing with the SDAT.

2. The issuance of the Shares has been duly authorized and, when and to the extent issued in exchange for the Units in accordance with the Charter, the Resolutions and the Partnership Agreement, the Shares will be validly issued, fully paid and nonassessable.

The foregoing opinion is limited to the laws of the State of Maryland and we do not express any opinion herein concerning any other law. We express no opinion as to the applicability or effect of any federal or state securities laws, including the securities laws of the State of Maryland, or as to federal or state laws regarding fraudulent transfers. To the extent that any matter as to which our opinion is expressed herein would be governed by any jurisdiction other than the State of Maryland, we do not express any opinion on such matter. The opinion expressed herein is subject to the effect of judicial decisions which may permit the introduction of parol evidence to modify the terms or the interpretation of agreements.

The opinion expressed herein is limited to the matters specifically set forth herein and no other opinion shall be inferred beyond the matters expressly stated. We assume no obligation to supplement this opinion if any applicable law changes after the date hereof or if we become aware of any fact that might change the opinion expressed herein after the date hereof.
