Great place in a great neighborhood!! My friend and I stayed here for 3 weeks and honestly, it was the best decision ever.
Location-wise, apartment is around the infamous brownstone Stuyvesant neighborhood, so it was picturesque during fall. Around 10-15 minute walk from the subway (lines A/C) so I would say it's very accessible. There's also a nearby bus going to another subway station so there's always another choice if you feel like 10 min walk is a bit far (not a problem for us though since walk was so picturesque). DUMBO and downtown Brooklyn are very near (around 15-20 minute metro ride), and it's around 45 min-1hr ride to Manhattan. Honestly not really a problem since the A/C lines go straight, so most of the time you won't need to change lines.
Apartment-wise, it was beyond our expectations!! My friend and I have enough space between the two of us (plus 3 huge luggages, and a couple of travel bags). Kitchen is just enough for two people, and all the appliances were in working condition. Tal was also very responsive to any questions we have. There's a laundry upstairs, but since the dryer wasn't working, we opted to go to the nearby Stuy Wash 'n Dry. Towels and change of sheets are also available, if every you'll stay there long enough to need them. Just take note that staircase is a bit narrow (but honestly this is normal in nyc), so just take care if you have big stuff to lug around. Room is on the 2nd floor though, so it's not like it's a long trek from the gate. Heater is automatic though, so if you're easily cold just take note.
Overall, this is such a lovely place that made our 3-week vacation in NYC absolutely perfect!
