My girlfriend and I stayed at Starlee's for one week and we loved the place, especially the area. Williamsburg is such an amazing neighbourhood! The apartment has a really cool interior and had all we needed (we only had a few problems with the sockets and our adapters!); it is also very close to Bedford Ave metro stop (L line). Following Starlee's suggestion, we tried the japanese restaurant in Grand Street, Samurai Mama. The food was amazing, especially the pork gyoza! There are two markets nearby, a Foodtown and a Whole Foods Market. And everything else you may need really...
Long story short, we look forward to going back!
