I hate to say this because it's something i read on craigslist today but someone who lives at bonnie ridge posted that he's caught 14 mice in 3 months

. Another person who lived in the same apartment complex replied using craigslist saying the original poster could get a cat for only $30 a month who'd keep his place mice free. The second poster did mention they have a mouse in their unit. If you type "mount washington" in the search tool on craigslist under the apartment listings, it should come up with both posts as well as others. I'm sure the original poster is someone who didn't know what they were getting themselves into when they signed their lease. I've been there before, and trust me, i practically lived in someone else's house, coming to my apartment just to pick up mail and a few stuff.
If you're ok with mice, then i guess you should take this with a grain of salt but personally, i crossed mt. washington off my list when i read that today. Maybe you should get a cat... that'll take care of it.
