Pros: Lovely is a powerful search engine for apartment listings with a beautiful user interface. Set specific financial, geographical, and listing parameters, then get search results delivered to your inbox as soon as they're available. The map on the site's homepage is auto-refreshed as new listings are posted and also clearly shows the geographical boundaries of all of the selected city's neighborhoods. We also love the bookmarking feature, which lets you keep tabs on the apartments you've contacted, all in one place.
Cons: The zoom function on the map is a little buggy, and zooming in too far will yield no results if there are five or fewer listings in the designated area. It's also not entirely Firefox-friendly but will work just fine on the Google Chrome browser. The site doesn't include any search parameters for those looking to rent a room or share a room. While Lovely doesn't have a mobile app currently, it's planning one with a Fall 2012 release.
