delivered the opinion of the Court.
This is an interlocutory appeal by the People from an adverse ruling of the District Court of Pueblo County sustaining a motion to suppress -evidence seized- under a search warrant. We reverse the ruling.
The trial .court found that, the search warrant did not sufficiently identify the premises to be searched, as required by the Constitutions of the United States and of the State of Colorado.
The warrant described the premises as “basement apartment at 502 Morrison Avenue, Pueblo, Colorado.” ■There was no reference in the warrant to the name of the occupant or tenant of the particular apartment sought ■to be searched. Consequently, a “particularity” problem under both the federal and state constitutions - arises, *432because there were two “basement apartments” at that address. Defendant contends that the failure to describe the place to be searched with particularity invalidated the warrant.
The question for our determination is whether under the circumstances here the premises were described with sufficient particularity. The Fourth Amendment to the Constitution of the United States and art. II, § 7 of our state constitution were designed primarily to prevent unreasonable intrusions into the sanctity and privacy of the home. The Ventresca philosophy, expressed in this language, should guide us in answering the question:
“. . . [W]hen a magistrate has found probable cause, the courts should not invalidate the warrant by interpreting the affidavit in a hypertechnical, rather than a commonsense, manner. Although in a particular case it may not be easy to determine when an affidavit demonstrates the existence of probable cause, the resolution of doubtful or marginal cases in this area should be largely determined by the preference to be accorded to warrants.” United States v. Ventresca, 380 U.S. 102, 85 S.Ct. 741, 13 L.Ed.2d 684.
We have two cases which bear upon the problem. The first is People v. Avery, 173 Colo. 315, 478 P.2d 310, in which Mr. Justice Lee, in construing the provisions of the Fourth Amendment and art. II, § 7 of our constitution, observed:
“Immediately apparent from a reading of these constitutional provisions are the requirements that the house or home to be searched must be particularly described or described as near as may he. It is difficult to lay down any test as to the sufficiency of a description which can invariably be applied to all situations and all circumstances. However, certain overriding considerations have evolved which may generally control and guide the magistrate in issuing the warrant, depending upon the nature and character of the place to be searched. A basic *433consideration is that general or blanket searches are forbidden, such being the very evil sought to be protected against by the adoption of the constitutional provisions against unreasonable searches and seizures.”
Avery, on the facts, is distinguishable from this case. In Avery the warrant described “the entire multiple-occupancy structure by street address only.” An examination of the testimony of Officer Koncilja in this case suggests that from his surveillance and the information furnished by his informant that he had no knowledge of the fact nor any reason to believe that there was more than one basement apartment. He could not determine from his observations whether the people entering the house lived in the basement or upstairs, because “... there is a high block wall I would see people go into a side door on what would be the north side of the house, but I could not tell whether they went upstairs or walked up a few steps to the main floor or where. Likewise with the back door, I couldn’t see adequately whether it went downstairs. My informant told me it was the downstairs apartment where Mr. Maes was living; . . .” (Emphasis added.)
The officer testified he had never been in the basement before. The record is also clear that this was not a general exploratory search which is the evil the constitutions were designed to protect against. The officers went into Maes’ basement apartment with him. They searched only the apartment which he shared with another individual. The actual search was limited to Maes’ bedroom and the rooms which he shared in common with the other individual.
This case falls within the spirit of the exception of People v. Lucero, 174 Colo. 278, 483 P.2d 968, the second case, wherein Mr. Chief Justice Pringle said:
“. . .We hold that the rule in Avery is subject to an exception, among others, where the officers did not know nor did they have reason to know that they were dealing with a multi-family dwelling when obtaining the war*434rant, and providing that they confine the search to the area which was occupied by the person or persons named in the affidavit. For a collection of cases, see Annot., 11 A.L.R. 3d 1330, 1334 (§ 8) (1967, Supp. 1970).”
Here the police officer in obtaining the warrant and the judge in issuing the warrant acted in the utmost good faith in attempting to conform to the constitutional mandate. The place searched was the place specifically designated in the affidavit and generally described in the warrant. Here the officer described the place as nearly as he could.
The fact that the apartment was occupied by Steven Maes was relevant to the probable cause, as that related to the requirement for the issuance of the warrant. However, at the time the warrant was issued, on the basis of the information then available to the officer, it would have appeared to constitute superfluous description. In short, Officer Koncilja did not know nor did he have reason to believe that the basement contained more than one apartment at the time the warrant was issued. People v. Lucero, supra.
It is conceded here that the affidavit sufficiently described the place, to be searched because it identified it as “Maes apartment.” The warrant, admittedly lacked this specificity. But that deficiency did not result in the illegal search of the other basement apartment — nor of any of the quarters occupied by others on the main, or second floor of the house.
Under the circumstances here, where the police officer who was the affiant- in the affidavit which identified the premises to be searched as “Maes apartment,” also executed the warrant resulting in a search limited, in fact, to Maes’ apartment, the warrant was sufficient.
Ruling reversed.
Mr. Justice Groves concurs in the result. *435Mr. Justice Lee and Mr. Justice Erickson dissenting.
