We stayed here with our 21 year old daughter and the apartment was the perfect space for the three of us. We had our own bedrooms and the living area (lounge, kitchen and balcony) was plenty large enough. The shower in the bathroom was excellent - something that I always measure good accommodation by.
There was a heatwave while we were in NY so we really appreciated the ceiling fans and the AC units - and the balcony.
We absolutely loved Sunnyside which is a really nice residential area with easy access to shops, bars and restaurants. Also the number 7 subway line was just a 10 minute walk (max) away and went straight into Grand Central giving easy access to everywhere else. Also the end of the number 7 line (beyond Grand Central) brings you to one end of the Highline - a feature not to be missed.
As well as going into NY city we also stayed in the local area visiting Jackson Heights (a really good shopping / eating out area) along the 7 line towards Flushing and we did a 15 minute walk from the apartment to the Museum of The Moving Image (MOMI) which is based in the old Astoria Studios. This was a definite highlight of our trip. Also, the Mexican restaurant opposite was really good.
We ate locally a few times - the best value and nicest food was at Bistro 64 just before the Sunnyside subway station (Bliss Street). We also enjoyed Pete's Diner one stop from Bliss Street subway station towards NY. For lovely breakfast pastries and everything bakery (eat in or take out) we really enjoyed Paris Baguette in Sunnyside itself. For food shopping - Freshnsave also in Sunnyside offered everything you could possibly want and best of all if you are over 60 (which I am) there's a 7% discount on Wednesdays and Fridays - I do like a discount.
All in all we really enjoyed our NY trip which was all the better for having stayed at Steve's place. We really got into the vibe of Sunnyside and felt more like residents than tourists.
