I recently enjoyed a great five-night stay at Pascale's place. The apartment was as advertised, a small, bright two-room in one of Paris's quieter neighborhoods. Nice view over the Passy reservoir from the office! Kitchen is well-equipped and there's a comfortable double futon-bed. Wifi access was stable for me, despite other reports.

The 16ème is a mixture of residences and upscale office buildings (international airlines, embassies, etc.). For a more vibrant evening/night scene, hop on the Métro (lines 1 and 2 are nearby).
