We use in to describe the physical location of something as part of a larger thing or place. We use at when we're talking about an address, a public place or building (a bus stop, the Post Office, the library etc.) and cases in which the location is irrelevant but what we do there is what matters (school, the dentist, dance class etc.)
Use the simple past tense (and not the present perfect) for an action complete in the past at a stated time.
When a sentence has a word or a phrase denoting past time, like yesterday, last night, last week, last year, then, ago, etc., always use a simple past tense.
It's better to use keep for a more or less permanent resting place, and put for a temporary one.
