Sunnyside is a very nice and convenient neighborhood. Lots of transportation options (7 train, Q32 and Q60 buses to manhattan, Q39 along 48th avenue to LIC, BQE, LIE, Queens-Midtown, etc). There are lots of irish bars, great restuarants, coffeehouses, markets, everything you could want. I find myself not going into manhattan unless i've been invited to a party or something. There's no need. However, if you depend on public transport, you're out of luck. the 7 is very slow and stops and starts constantly, and it breaks down much more often than it should, especially in summer, and that creates delays for a few hours afterwards (they don't get their act together very quickly). Since we have no express stop, I often see 3 express trains going into Manhattan and at least 4 trains going in the direction of Flushing before just 1 local train to manhattan arrives at 46th street. And now the MTA wants to cut service. The Straphangers survey will try to tell you the 7 train is the second best train in the system, but that is a big lie if you actually have to use it.
In a few days, I am moving to Woodside on the R,V line. I'll let you know how it goes.
