Just because you're a budget traveler doesn't mean you have to sacrifice comfort and style. A new breed of extended stay hotels is putting a sophisticated spin on long-term lodging. Among them is AKA, a chain with eight hotels in cities such as Philadelphia and Arlington, Virginia, and plans to open locations in Los Angeles and London this fall. Each hotel has sleek, modern suites with a bedroom, living room, and kitchen. Other amenities include a business center, free Wi-Fi access, and a Zipcar account. Not too bad for $195 and up per night. Website: http://www.hotelaka.com

Until recently, online video chat services have been relatively bare-bones, better suited for a call to Grandma than a client. The beta version of Skype 5.0, currently available only for PCs, allows video chats with up to five people, so you can hold videoconferences while traveling. You can share your screen during calls and record videos using an add-on. The price for all that functionality? Free. Website: http://www.skype.com
